I doubt there's any date info there - the yoke is a forging, not a casting, and the Chevy bowtie emblem indicates that it was made at the Chevrolet-Detroit Forge Plant; the number next to the bowtie symbol relates to the forging die set used to produce the yoke, not a date. Forgings weren't dated, but they carried the forging number for the part.

Chick, what car was that driveshaft from?  Your 68 Z28? 

If so can you post the length from center of u joint to center of u joint.  Thanks.

Yes, the drive shaft is off our 68 Z/28 and the length is 52 1/2". I found the part # on the yoke but its very difficult to read other than a couple numbers.

Has there been any definitive conclusion on the drive shaft strip color coding for the 1st Gen drive shafts, specifically the '69 Z28?

The Muncie Transmission input shafts were different between the M20 versus the M21/M22 with the number of spine teeth.  But were the output shaft splines the same on all three Muncies?  If the output splines were different, did the draft shaft strip color codes reflect this?

Based on the related links, it appears that the orange/white stripe combination has been found on 1st Gens.


Thanks!

Thanks William! Bryon, the info I supplied was from what I believe to be a 69 Camaro auto. trans and not my 68 Z/28. What a mistake but I had the wrong drive shaft! The yoke on the one I reported on is larger and will not even fit in our M21. After William's comment I thought I better double check and yikes, screwed up on this one. Will report on the 68 Z shaft after I complete the intitial cleaning.  Can tell you the yokes are offset and the length is approximately 50 1/2" in length.

Chick, can you double check that measurement?  I need the measurement from the center of one u joint to the center of the other.  I believe it should be 49.96 inches for a 68 Z28.  Thanks.

The Muncie Transmission input shafts were different between the M20 versus the M21/M22 with the number of spine teeth.  But were the output shaft splines the same on all three Muncies? 

Based on Corvette specs, all Muncies through 1970 had 10-spline input shafts and 27-spline output shafts; that changed to 26/32 in 1971.

Dave we are still working on figuring out the driveshaft paint stripes.  There were differerences, but so far we have not found anything written down.  So we are looking at examples at this point.  

As John says, all output splines on 67-69 Muncies were the same.  The large 32 spline output shaft did not start until sometime in the 1970 model year and used the 3978764 tailhousing.

I could be wrong but I think those are the AMA specs for use with the 396 engine with manual transmission.  I show 49.96 for all L6 and small block engines.  

Kurt S., Ed B. and I have gone through all of the parts books and AMA specs and have come up with a list of numbers.  I don't think we are quite ready to put those out there just yet.

The point of this thread is to find the lengths of ORIGINAL driveshafts to confirm what we have found so far.  

If anyone has an ORIGINAL driveshaft and would be willing to share information it will be greatly appreciated.

Original 1968 Z28, Norwood, 07C, 50 inches (or darn close), staggered yoke alignment, orange and white stripes (13 inches from centerline of yoke to center between the two stripes), attachment looks like u-bolts that are flattened where they go around the u-joint.

Thanks for that information Jerry.  I believe the 50 inches (49.96) and u-bolts are correct.

Thanks for all of that information Boston14.  Exact length from 1969 AMA information says 49.56 inches.  So yours appears correct.  Thanks again.

Took it out of my cleaner set up and it seemed to eye ball just under 50". Yoke ends have the staggered offset, U bolts, and beginning of orange/white stripe is just over 5" from centerline of yoke. Yoke had both orange and yellow paint on it. Plenty of orange paint on that yoke. When I flip it I will report any new findings. Some pictures:
