What Axle Ratio Do I Have?
Here is my SPID. I have a 1972 C20 with L47 402 CI big block, the G70 rear leaf springs, and M49 turbo hydromatic transmission. On the build sheet under axle it shows "R K H".
Looking at page 9 of the 1972 Chevy truck specification manual from the GM heritage center it shows I should have a Dana 5500 rear (what the heck is that?) and 3.54 axle ratio since no optional axle ratio is shown on the SPID. Do I have this correct? Thanks!
