the spring perch width is different, i believe. otherwise you should be good on WMS widths.

A fella purchased a rear end from me from a 91 C2500 I was parting out.  This was for an earlier GM like ours and said it was the right width but he had to redo the spring perches, but I haven't measured it myself, the truck is long gone...

spring perch width is different, you have to move them as stated.
