Broke a oil ring on piston when installing. I know I'll need to buy one set but can't find it anywhere. Its for a mahle piston .20 over in a 99 5.9 cummins. Every place I've called said 2-3 weeks out. Mahle is apparently on strike right now. I know somebody out there has one but can't find who. I've called a bunch of suppliers and got the same answer. Any help would be appreciated. Thanks Shaun
