Driveshaft with sye...

I did a search but couldn't find a specific answer.

For you guys running a front XJ shaft in the rear with your sye what years did you get it from? Should I be looking at LP years and what lift are you at? I have an 88 with automatic transmission.

Thanks!

After reading many searched threads I've found so many different answers that it seems like a trial and error situation. I guess I'll cross that bridge when I get to it.
