To make full use of my yoke I could make my driveshaft 2" longer and still have room to back it out of the axle with 3/4" to clear the cap that is 1/2" deep on the pinion.Do you know what you have yet?

no. been busy. If i have time today i will pull the shaft out and measure the slip yoke. Looks like my drive shaft is 1" too short at the moment. Gonna call strange if i need a new shaft.

I am lucky there is a place near me Custom clutch and u joint in Cleveland I just drive to in 30 minutes.Keep us posted.

Ok, i have some pics. now, from the base of that slip shaft to the edge of the boot measures 2", but the main shaft is out past the boot 1/4".

couple more. The yoke is splined to the bottom and measures 5.5" deep.

couple more. The u joint measures 3" from the pinion saddle.

what length of drive shaft should i order?

I think if you put a jack under the pinion the length will be a little shorter but maybe only 1/4".No takers on the length?

So that 3" is with the yoke all the way in the trans?

If you order from Dr. Diff, he asks for two measurements, and some other questions, of course. But Idk if you have to call to have something other than a 1350 joint shaft made.

yes, with it all the way into the trans. I calculate 2 3/4 of spline engagement statically. Probably 3" under load. Enough or do i need a new drive shaft?

I would go with a 46" ds but I fear the rubber boot is still holding the yoke out.

The boot flattens out when i slide the yoke all the way in.

The cove on the yoke should go to the trans housing not the boot so you need to add the boot length.

I would think if you took your measurement with the yoke cove just back from the boot 1/4" to 1/2" the length would be good to pull the u joint from the pinion and have room.I think this will give you the 1" you want to be able to move it.

Yep, yur right. Just spoke with Dynotech drive shafts and they suggest 1" from pinion yoke. Shaft should be 45.5" to be correct. 2 3/4" Spline contact is enough for strength. The problem is with the front u joint to far away from the tail shaft bushing support.

Thank you for your information you got!How much do you think a new shaft with ends and joints will cost?250$Wait I bet with new ends,ballance will be more like 350$

My guy said 335+tax 3.5" mild steel new ends,joints weld balance 2 days tops.
For anyone in the area 216-431-1630 3417 St Clair Ave Cleveland Custom clutch n joint

No problem. My current drive shaft is from Dynotech. They quoted me $415 without slip yoke. Gonna call Strange yet. Thanks

Sorry, if off topic, but how thick is the caltrac mono leaf front segment?
