so i found out today my crankshaft is scarred pretty bad from a jackass re-using an old oil pump seal so... now im looking to buy or trade for a crankshaft.
my question is what is the difference between all the d-series crank's? and are any of the interchangable?

 

I believe you could use a d16y7 or d16y8 crank but i'm going to check and make sure.
