Can I fit a 1.25 spacer on rear with Boss 20x10? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am going to mount Boss 20x10's with 1.25" spacer on the back of the 67 but the rearend is the wider 70 rearend. Anyone running these sizes? The Boss wheels have a 6.25 Back space, so calculating, it should work. Please tell me your drop and rear tire size too. Thanks.

Thanks for the input. What drop and tire size are you running? how much room do you have between the inner wheel well and back side of your tires?

Any other examples of people running Boss 20x10's in the rear? Adapter/spacer sizes?

I agree,... a 1" spacer would be better with the wide rearend.
1-1/4" to 1-1/2" for the early narrow rearend.

I'm running 1/4" spacer to clear inner fender with 20"x10" wheel.
