ello ,i find original drive shaft (propeller shaft) for my 69 Z/28 M21 but i dont have the slip yoke :'(,
what is the GM part number ? or the Length to center of u-joint
Thank you
The original # was 3950364 then was changed to 3967732 and then was changed to 14075214. Hope this helps!
The driveshaft used for 1969 Camaro w/Muncie 4-speed was 49.56" C-C on the U-joint trunnions. One of the several service part numbers was 3970521.
The production Z/28 driveshaft remains controversial. They are often seen with the trunnions aligned; for other Muncie applications they are offset as usual. The Assembly Manual does not list a part number. It is possible in production, Z/28s used a driveshaft balanced to a higher rpm.
For the record, 67-68 driveshafts are longer and used different trunnions. They don't interchange with '69s.

The 69 slip yoke for M21 is not super special.
I was kind of thinking that other than the 400 turbo they were pretty much the same.

They used the same shaft as any 69 with a manual trans or powerglide. Nothing special....
