ok, so i know that L series main bearings work for the mains, so is that the same for the rod bearings or are they fj specific con-rod bearings only?

and also, is there any way to use L series Rod/Main bolts?

and does anyone know the ARP part Numbers for the lower end bolts

did search and couldn't get an answer, also I'm in the US so I'm looking to use as many L series parts as possible

A1. FJ20 rod journal diam. is 49.961mm-49.974mm same as ALL L series engines, including L20B.
Reasonably sure I used L series bearings for both mains and rods.
A2. Don't know, you would have to compare them.
Standard fasteners are adequate and are re-useable.
A3. NISMO might be a better source for main cap bolts but once you determine what size they are,
ARP might be able to match them??
