70’ Duster 340 4 speed value
I will did this. Since you say know your of B Bodies, I look at the price structure in general like this. You know what a restored 69 roadrunner 383 4 speed car brings, then adjust down from there.
I agree with post #9 above it is all in the details and condition. Personally I deduct a bunch for headers in a #'s desirable model. Just one small thing.
