Drive shaft assy front L=709MM 04/2010 05/2018 26208605866

Drive shaft assy rear L=1410MM 26107564398


So what I found was this- 35d is 705mm/1410mm and the 50i is 709/1427. But again, I'm not certain if these differences mean anything because I'm not suer about the transfer case. So, is there a way to see if the transfer cases have different lengths on their flanges? If the differences are because of the difference in the transfer case, then my transfer case and both driveshafts will work fine. If the differences are on the diff flanges on not the transfercase, I'd be looking at having to either replace my transfer case, (not happening), or I guess swapping both driveshafts with that of a 50i.

I guess the driveshaft swap is likely cheaper than the transfercase, but either way it makes it a hair too complicated for me to try on the car I need to drive to work in.

Again, if the difference in length is because of the way the flanges are on the TCase, then everything should both up nicely. If I had a mill and could make an aluminum spacer and use longer bolts, I would go ahead and order the diffs now. But I don't have a machine shop to make spacers for the cost of the aluminum, so I'm not sure how I would guarantee a successful install without knowing where the difference in lengths comes from.

The more I think about it, the more I'd really like for this to be possible. Just wish someone had done it before!
