Re: 63' Chevy C30 Dually Rear End Identification
You have a 5.14 ratio. Your rear is an HO52 or more likely HO72 (center section is interchangeable between the two). The only other ratios available are 4.57 and 4.11. You will have to find a used one. Best place to find a 4.11 is in a late 60's early 70's truck,
Good luck, Tom
