I guess AAN ones are the same? Looking for a few sources just in case. Thanks

Still looking! Either that or AAN pistons. Looks like 3b pistons have a wider pin retention area than AAN pistons? I have AAN pins and they are about a 1/4 inch too short but fit perfect :(

I tore apart the blown block to find the second cylinder rod bearing chewed to death. However my old wrist pins were in magnificent condition lol.
Here's a breakdown of length dimensions for everyone's reference:
AAN = 2.237"
3B = 2.432"
This does make me feel better about durability of the pins in the 3b pistons though! More surface area should make them more durable I'd think
