AV8R4AA is on a distinguished road
I always assumed the dimples are “lightening” holes.
I’m talking weight and mass, not thunderstorms.
Both of the crank flange ARE the same part number.
I would presume that they would bolt up the same.
If the diameter is different than I am at a loss.

My goal is to keep the old redhead on the road. Not break the bank.
I have not checked yet, but a different diameter should require a different belt.


JUST CHECKED
Different serpentine belt part numbers.
Guess I need a new balancer.
