ABS Driveshaft with NON ABS Differential (Welded Diff)

[hellaslows13]

Hey guys, I really need some help. I did some searching around but have found a ton of mixed answers that did not answer my question.

I have a 95' SE with ABS. I have an ABS Drive shaft. I replaced my ABS VLSD with a NON ABS Welded diff. I also installed subframe risers and new poly diff bushings. I noticed that there was a gap between my diff and driveshaft and was wondering, how bad is it to drive it with the drive shaft being pulled on? I've been driving like this for a few months, what could i have damaged? Also, what can I do to be able to run my welded non ABS diff on my ABS car? Do I just changed the drive shaft to a NON ABS?

I appreciate all the help, thanks.
