rear end swap, 7.5 to8.8
 

Is there any driveshaft mods that need to be done when switching from a 7.5 to an 8.8?

nope..just swapped a 4 banger rear out for a 8.8..i did use a aluminum driveshaft but the old driveshaft will work

I didn't a single problem doing the 7.5 to 8.8 swap either. It's a direct bolt in. No driveshaft problems here either.
