I've got a set of roller lifters I pulled out of a 1992 z28. I ordered a set of Comp lifters and got them in, then found out I could have reused my old lifters. There's nothing wrong with them at all. They are in great condition. I don't know what brand they are but seem to be good quality. Someone make me a reasonable offer plus $10 shipping. If it cost more than $10 to ship them I'll pick up the difference. I'll ship them USPS or UPS and send you the tracking number when they ship.
