I bought a urethane bushing set for my 78 280z. I had the old bushings pressed out at a shop. while installing, I found the mustache bar (differential carrier) bushings way large, maybe 1/4" play up and down, inside also. I spoke to the manufacturer, Prothane, only to be told the part # was correct. The other bushings appear to fit at this time. the box is labeled for my car.The fsm calls these bushings insulators. Is there a sleeve or something that may have been removed with the old bushing??

There is a metal sleeve that was pressed out that should have stayed! You're supposed to burn out the bushing with a blow torch and leave the metal sleeve in. I am not aware if there is any way to fix it short of a new mustache bar. At least they are cheap and readilly available. Guy

Thanks ! I had a feeling there was someting missing. Any recommendations on a supplier?

Roger at the Z Barn. www.ZBARN.com By the way, when you get the new one, you just light the rubber bushings on fire with a torch and she will burn up like a flare. Do it away from civilization as it makes a mess! Wire brush the inside mess and your new Teflon will fit as new. Good Luck
