looking for piston rings...

just wondering if anyone might be able to help. It's for a 3.5" bore, and the upper rings have to be 1/16" There seems to be tons of 5/64". only need enough for a 4 cyl. you ask what are they for...guess i'm prepaired for gettin some shit, it's for a 140cid vega motor. stock rings are 5/64, but these are TRW pistons..12.1 comp. I've checked with summit and jegs, no luck local speed shop no luck, just figured i'd check here.

thanks

 

speed pro part number r-9840 they are plasma moly file to fit 1/16 1/16 3/16
