Thinking about putting an LS engine in my 48. If I do, does anyone have any suggestions on what rear end to use that would fit?

What bolt pattern will you be running on the front? I assume you want front & rear to match?

55-57 will work. Just need to drill the spring pin hole 1 1/2 inch ahead on the spring perch.
It is 5 lug.

Yes the 55 to 57 has same perch locations, make sure your axles and R & P are beefed up though.
I used 67 camaro rear end, but I wish I used 55 t0 57 set, it was a lot of extra work relocating those perches!

Thanks!
