Ok I just took mesurments from my 52 rearend so I can start looking for a (used) new one. I got 55 in from flat on backing plate to backing plate and 39 1/2 from inside spring perch to inside spring perch. Not to worried about perch numbers since I will use new ones with kit from CPP but the other mesurment seems narrow to me given some of the numbers I have seen on here. Any one else got there numbers in that range. Thanks, Doug
