Hello!

I've got a '72 D100 with the 8.75" rear end that I'm looking to replace due to excessive wear to the housing. I've looked just about everywhere for spring perch spacing on the '72-'74 8.75, but in all the tables and charts I've seen, they're notably absent. I took a measurement of the springs on mine to guess the c-c spring perch spacing (43 1/4") and I was curious if that lined up with anyone else's measurements or books.

Thanks in advance!
