I bought a 72 coupe today and it came with a ton of spare parts and 2 spare 327`s. The only thing I can`t figure out is the extra main and rod bearings that came with it. There is a box of Michigan R-7020-CAP rod bearings and 4 pair of 7022 AK and one pair of 7023 ACAP main bearings. Does anyone know what these bearings work with.
