Finally remembered to post this:67 LOS, 11B build, L48 w/ Pglide49.5 inches center to center, yokes are # 3790024 rear is 280A and front 280DU bolts, axle is PC1031G 3:31, yokes are clocked
My '69 L48 is 5.5 inches. I thought when we rebuilt the driveshaft it was the wrong one but checking another for verification it was correct. My driveshaft is also clocked and that brought on a bunch of weird looks and a big discussion at the shop until the post about the drivehsafts come up.
I think that I know why there is a 1/2 inch difference in driveshaft lengths between the '67-68 and '69 driveshafts but want info to verify. I believe it is because there is a difference in lengths of the transmission yokes being used for these years. Can anyone measure their transmission yokes from center of u-joint to end of yoke and report their findings. Be sure to include what year yours is. They should measure either 4.875 inches or 5.5 inches.
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 cross member 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.
