Finally a HUSKER again
So I have my tranny out, and the column is out also, so I can see all my pedals good and I see a problem. The factory linkage rod from the pedal to the z bar has a huge hole that slips over the stud, and has a retaining clip that is always a pain to get into place. Well I have everything out, and at my reach and I was going to cut the crappo stubs off, and make a rod with heim ends on it to eliminate the sloppyness. Also gona do the same with the clutch fork push rod. Has anyone ever done this and is it worth the time to do that? Also I read in the mopar muscle to lengthen my pedal linkage to 6" for a better ratio. Will all these combined be a good idea, and aid in how smooth the clutch feels?

Kasey the heim joint idea is well worth the time and money.When I re-fabbed my clutch linkage I just marked where the factory arms were and made my own arms off the Z-bar tube.
You can use a 3/8'24 female heim for the adjustment rod.I suggest thick wall tube for the rod from the pedal to the Z-bar

I have done both. Off the pedals I use 1/2 rod with yolks on each end with 3/8 pins. Then down below I use 3/8 rod and yolks again. I haven't used heims that much but should work too.
On the z-bar I changed both levers to change the ratio and for clearance. With the solid rods I could just put slight bends in them to get nice straight zero play push. Plus it allows for multiple adjustment sites for TO bearing clearance pending how much gap you need.
Good luck

What do you mean by yokes, Im talking about the heavy duty heims used in dirt car racing that are VERY durable. These are stainless steel, and tough as nails!

If your familiar with semi trucks the same things used to hold the brake chamber push rod to the slack adjuster. They see millions of cycles and are used in clutch linkage, throttle linkage and other areas. I have places where I can get a variety of sizes quickly and locally.
They are shaped like a U with the base threaded and a pin through the "forks" that you cotter key in. Just allows for quick&easy disassembly. Like you said though, and Gus, heims are more than adequate especially if you know what ones to get.
Good luck

I see what ya mean now. And they are usually cast steel.

I like that idea also. But I have a hand full of heims, and I can get a little adjustment out of them.

Nope, they're "forged".

Old pedal to z bar link. I modified this one before to take the slop out of it, but this is way better.

Is there any tricks to setting up offset dowels? Also Has any one here ever used mobil 1 5w30 or 5w20 oil in their 4 speeds? I have read, and driven a few cars that had that in the trans and it seemed very nice.

Don't do it in a 8 3/4 rear end I use to use straight ATF type F in my slick and pro shifted NP 833 Hemi trans when I raced NHRA stock, never had a lubrication or heating issues that I was informed of or saw from Doug Nash or Joe Liberty when they did and redid my gear sets later after every 40 to 45 runs

Im gonna run 5w20 mobil 1 in it. Idont plan on bashing it like any NHRA class racing, and Im not one to just pull gears, Ill clutch it.

As far a the bell housing dowels, I think im gonna lock tight them in place for sure, but can I dial this inn with a flatblade screwdriver, or am I going to have to pull them out every time to get it "correct"?

they should be tite enough to not need locktite.
most complain to tite.
tial and error, measure old dowel vs new and note difference.
put new dowel in drill press or drill and polish to comfortable fit.
Not too tite to be a hardship, not to loose where they turn freely.
At least thats what I do.

I bought the dowels that are on here as a sponsor. Can clock them and use a set screw to secure them.
