I'm putting a 1990 suburban 3/4 ton 14 bolt rearend In my 72 Blazer the rear leaf springs are 56" measuring A-26 & B-30 My question is does the 26" measurement go to the rear hanger or is the 30" .Thanks for the help

The extra length goes to the rear. It's a simple matter of moving the rear spring mounts back because the frame rails run straight. Actually, not so simple on a Suburban or K/5 thanks to the fuel tank needing to be dropped
