I bought a set of eagle rods, and some stock reproduction pistons, not realizing that I would need pistons with circlips.

do any aftermarket rod manufacturers offer rods for press fitting pins?

or will I be stuck with using stock rods unless I get different pistons?

 

Take the pistons to a good machine shop and they can cut the necessary grooves in the pistons for you.

 

ok, great.

so where can I purchase the piston pin circlips?

 

http://www.raceeng.com has JE spiro-locks in D or B series pin diameter--they are like $1 each. Give them a call. Just make sure you get the grooves cut in the pistons that will match the width of the spiro-locks, if that is what you intend to use. You can also use wire locks or snap rings.
