So, the more I look, the more I think this should work. The rear diff, has all the same seals, so I'm guessing it'll bolt in.
Same hub wheel bearings in the rear, same output shafts in the rear. That means the flanges will be the same.
On the front end of the diff, the nut seems different, by 4 mil, but the seal is the same. So a possible difference in gear size, but the same seal lead me to believe the overall fit would be similar.

This brings me to the driveshaft- the driveshaft has different part numbers. The bolts and nuts to bolt the transfer case are different. which led me to look at the transfer case. the LCI 50i and all 35d's have different transfer cases- 50i has the ATC 450 and the 35d has the ATC 700. I guess the 35d needs it for the torque. Thinking through this, I don't think it'll be an issue on the front of the driveshaft, becasue I'm not changing that. Since the rear bolts and everything are the same, the only thing I'd need to worry about is the length matching up in the right way so that the rear of the driveshaft will bolt up exactly the same.


The transfer cases being different also make me worry about teh front driveshaft, from trans case to front diff. The bolt patterns look the same, but the 35d shaft seems to have a guibo, while the v8 does not. I'm not sure how to figure out the lengths of the two, and I'm not sure an equal length will necessarily mean it'll fit, since the vehicles have different transfer cases.
