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.

AMA specs for '68 state 50.46" c-c.

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.

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!

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.

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.

Rear axle housing is normally 40-60 percent gloss black.

MyRed67 - sorry I could not find your name isted - thanks for that information.  It goes along with what the length is supposed to be for 1967 Camaros with 6 cylinder and small block V8 - 49.96 inches.  The information on the u bolts helps too.  At this point, just started a database on the stripe colors.  If you could, list the color of the stripes in order from front to back.  I can't tell from the picture if the orange or white is toward the front.  If you find the casting number, please post that too.  Thanks.

Is ANYBODY out there willing to measure your original driveshaft and provide that information? 

Especially interested in Big Block cars...manual trans or TH400.  Thanks.

Rich,

Thanks for those links.  I had read most of them previously.  The offset question is probably not one that can be easily answered, but I thought I would ask people who had originals to try to figure this out. 

Maybe I should just take this one step at a time, but I figured if people were going to take the time to look at what they had it might be easiest to just get all the iinformation at once.

So for now...what I think I have figured out is the following for lengths.  This is from AMA specs and some other Chevrolet sources. For 67 and 68 cars with the 396, different frame mounts for the engine were used which pulled the engine forward about 1/2 to 3/4 inch.  Also note the holes for the 396 crossmember for use with a manual transmission had the transmission mounting holes about 3/4 inch forward.  The PG, TH350, 3 speed manual and 4 speed manual transmissions are all close to 27 5/8 or 27 3/4 inches long (including bellhousing length).  But the TH400 is slightly longer - around 28 1/4 inches.

67 and 68 Camaros used two different lengths.  49.96 inches for all applications except the 396 with manual trans which was 50.46 inches.

69 Camaros all used the same length, 49.56 inches.  This appears to be due to the frame mounts all being the same for the big blocks and small blocks.  Although I can't find anything listed, it seems the TH400 driveshaft should be slightly shorter.

So that is why I am looking for actual measurements, to confirm these numbers.  If anyone has different information, please post it and list your source.

Several people are working on putting together original driveshaft information for 67-69 Camaros. Items of most interest at this point are below.

If you have an original driveshaft and would be willing to post information about your car, it would be very much appreciated. Here is what to include...

Year of car
Norwood or Los Angeles car
Month and week of vehicle assembly
Engine
Transmission
Driveshaft length (measured center of u joint to center of u joint)
Type of attachment to pinion yoke. There are two types: U bolts and the strap and bolts method.
Code stamped on front of passenger side axle tube.
Paint stripes and a picture (if possible)
Position of the u-joint flanges on each end. Some cars were "in-line" and others were "clocked" about 30 degrees off from each other

Post in this thread if you want. If you would rather not post, but still contribute, send an email to me please. Thanks.

Bryon

*** Modified 3/18/2014 to remove casting number.  Most don't have it and it is a forging number on the yoke.  ***

Buy it now price is 6500 but will also let you submit an offer.  That is cheap if you own the car.  If not, probably still way too high.

I have your M22 case.  Assembly date is P9A24C.  I know that is quite a difference in date from transmission assembly to vehicle assembly but stamp appears genuine.
