so, are you saying they are a close enough fit (in length) to work?

FirstGen spring perches are set inword about 1.5" from the location of a 73up 14ff. My 2005 Duramax has rear disk on it's 14ff. I could measure it but I would guess the spring perch is too wide for a 'bolt in" affair. I do belive the axel length is the same still but I am guessing...

Yeah, I was talkin' overall width, not specifically perch measurement's.

There's always going to be custom work needed when you change em up.
