Hi Clair, I'm just at a local speedshop here in Hagerstown. And we are not pretty sure what Pilot bushings / bearings to choose. Do you have correct measurements, descriptions or partnumbers on hand? I would appreciate a response as I ever do....

Hey, Buschi,
Sorry for not getting back to you earlier, too much going on at home these days to spend as much time on Moparts as I'd like... 
I don't have a PN on the Toyota pilot bushing/bearing. In fact, I don't know if it is a bearing OR a bushing. I was counting on making a bronze/oilite bushing from some bushing stock that would press in to the Mopar roller pilot bearing sleeve. Going from memory  the sleeve for the Mopar roller pilot is about 1" DIA inside. The Toyota pilot shaft is small, though, APPROXIMATELY 0.454" . I would think that you could make a pretty durable bushing in that size, even in bronze/oilite.
Going over my old notes, which I wish were more complete, I show that the Toyota input shaft is 7-7/16" (7.438") long to the tip, and the pilot portion is about 0.75" long. I don't have the exact measurement in front of me, but I think I remember that the AX-15 Jeep/Dak bellhousing is about 1/2" deeper than a normal Mopar bellhousing (7-3/8"), so about 7-7/8" for the AX-15. That's what makes the pilot bushing issue "interesting". The crankshaft sticks out beyond the back of the engine block by 0.608" to the surface that the flywheel mounts to. The converter hub sticks out another 0.250", and that's what the roller bearing sleeve mounts in. The converter hub inside is 0.650" deep, and the roller pilot bearing sleeve is 0.560" thick, so you COULD press the sleeve in to the crank deeper than flush, but that's not useful to you or me.
I need to start mocking things up to see what's real, but *I THINK* that with the Mopar roller pilot bearing sleeve flush with the converter hub, there will be SOME engagement of the Toyota pilot shaft in to the pilot bearing sleeve. HOW MUCH, I'm not sure, as I put my spreadsheet together several months ago, and I need to rethink how I set up the formulas to make sure they make sense. If you can put an AX-15 bellhousing on a block, you can get some measurements to verify that depth, and then can compare them to the crankshaft measurements I have above, as I think those are good. Then it should be simple to see how well - or poorly - the input fits a stock roller bearing sleeve. Some simple machine work can make a bronze bushing, or a Toyota bushing/bearing might be made to work.
I'll try to get some more numbers tonight, I just made some space around my 318 mock-up block this weekend. Oh, and welcome to America! I hope you can find some good beer! 
Clair

Hi Clair, this is what you wrote before. Now the Speedshop here gave advanced adapter a call and they told him that they never made something for especially a Toyota Turbo Supra. Is it possible that Toyota shares the splines with an other domestic Tranny for that you asked for? We have a problem with ordering than when we don't know exactly what iit is...
Here's the clutch disk on Summit Racing's web site. Says available Sept. 22, so you may want to try to get it from some other source, or directly from AA. I doubt that they specified Supra, but the spline count and shaft DIA are common in Toyotas. Best bet might be trying one of the offroad shops, as Toyota trucks get engine swaps very frequently for more power, but the drivetrains are usually left intact.
Here's a google search for PN 716105
And here it is on AA's own web site, for only a few pennies more than Summit.
Hopefully someone will have one for you. And me, too...

Clair please send me another e-mail. I have a drawing that you can use to figure out your application depths with. By the way, I would look at a roller pilot bearing because of the small diameter of the input pilot. Let me know if I can be of any help. Tony Edler Classic Mopar 5 Speed tony@cms-grp.com

Tony, I'm not sure what kind of bearing/bushing the Toyota uses, but I'll contact you to bounce some ideas off of you when I get a little more info in hand. I'd like to see the drawing you have, as I'm always happy to benefit from someone else's hard work... Buschi, are you back across the pond? I hope you had a good visit, and were able to sort out some of your swap issues while you were here. Looks like I'm going to start gearing up for some progress here, too, although baby steps at first. Got my engine dolly modified so I could mount the trans to the rear of it and mock up some parts for real. This will be good. Clair

Clair, had a great stay! Looking forward to the next trip, hopfully next year.... How do you think to mount the odometer, speedometer? I forgot to buy the bearing/bushings for the pilot and pressure plate... me dummy!

 Hi Clair, I hope you had a great  ! Any news on your swap? I'm starting these days practically. The speedo cable connection question is still unclear. And new is how do think to mount the tranny. What kinda transmission mount? I just received a stock 4speed pedal setup from a 70 Dart. Now I'm thinking about how to connect the clutch master cylinder (system from the Dakota) to the pedal I have... Looking forward to hear from you soon.... Michael

Hey, Michael,
Sorry for not getting back to you on this earlier - it's been busy around here for the last few months! I think there's a speedo port on the trans, and somewhere I've seen an adapter for the Toyota trans to a more common speedo cable. I'm not on my normal computer, so I can't check my favorites to find the link right now. I'll see what I can find and post back, but I'm pretty sure there's a way to use the mechanical speedo with this trans. I've been concentrating on the electronic speedo for my swap, but I've seen both.
Not much progress on my end, but I have been experimenting with a different bellhousing setup. Need to find the proper starter motor to see if it fits the 10.5" clutch I have as an option.
Hope all's well over there, and I'll post what I find.
Clair

OK, here's what I'm finding on the speedo cable situation... going back again to the catalog at Castlemain Rod Shop, they show a cable that SHOULD adapt to a late Mopar clip-on like yours (SC2), or an early screw-on unit (SC1). The SC1 SHOULD also work on aftermarket speedos like Auto Meter as well. I don't think I want to order one from Australia, as there MUST be SOME local shop that can build a cable for me/us. Another source (more local to me, at least) is Jags That Run / Stealth Conversions. They have a couple options for speedo adapters and Vehicle Speed Sensors. Might be worth a call/email to see if they can source a cable, too, but it might not make a difference if their adapter will let you hook your cable up directly. Hope this helps... Clair

Hey Clair, if memory serves, you were concerned about the length of the Toyota yoke. Correct?
Reason I ask is Greg posted a clip from some other forum with an aftermarket yoke part number on slantsix.org, so I've been doing some research. Part number doesn't match with anything but I did track something down to a manufacturer in Australia (Hardy Spicer).
Long story short, it doesn't appear that the spline engagement is much shorter than a Turbo 400 yoke (per the manufacture’s info) at 4.530" vs. 4.685".
Part # posted was 3-3-3558. Best I can tell, the part # should have been 21R-3-3558, but that is for a 23 spline yoke and the R154 has a 21 spline output shaft. They show two part #'s (2R-3-3188 and 21R-3-3208) for Toyota 5 speeds with 21 splines. In theory (per the forum clip) one of these would allow a larger 1350 u-joint, but the numbers I found for the 21R stuff shows a u-joint cap diameter of 1.078" which is much smaller than 1350 u-joint cap. The 2R stuff was even smaller at 1".
Just some more info, thought I would share.
