8.8 swap
In short (no pun intended!!) if the driveshaft is a little short after the install, it would be cheaper to use this spacer then getting a driveshaft made.
There are post such as no. 49 that speaks of moving the rear back 1in. .......
I just felt that it may help some who are converting to a 8.8.
This particular adapter is aimed at mustang guys who do a transmission conversion and the driveshaft comes up 11/16 short. There are other spacers as well.
FWIW I have a 87 dakota 4wd, stock suspension. I pulled the 8.25 rear and put a 8.8 under it. For some reason, my driveshaft is out of the transfer case by 2&3/8 in. with the truck setting on its wheels. Part of it is where I converted from a NV2500 to a NV3500 transmission. The bigger transmission is actually 3/4 in shorter. So that is part of my problem.
I have received a lot of good information from this thread, as well as this forum, especially the magnum section!!
Thanks to everyone who post up what they have found and their experiences....
Again, in short, the reason I post this? To help out anyone who may have a slightly short driveshaft and save them the money of a new driveshaft.
