How do I go about it? I doubt there is one fitted but following my discovery of a forged engine I've been told by someone that thinks they know my car from years back it used to have a Quaife gearset. It's not all that loud and doesn't whine so I doubt it has one now. I'm tempted to check anyway, just in case. The gearbox is in the car currently although the engine is out. I guess you can't tell from the bell housing end? If I pull the back of the gearbox off, would something be stamped Quaife?
