I've got a metco 4lb lower that I'll no longer be using. The hub that the ring attaches to had the area that attaches to the harmonic balancer shaved down about an 1/8th inch so it would line up with my pullies. It's been leveled so no need to worry there. If it is in too far you could easily shim it out to where it needs to be. It's on the car and I'll be removing it to get pics up soon if you want them. I doubt anyone can beat this price either, I'm asking $215 shipped firm.
