Hi! I've had no luck finding a definitive answer to this. I'm trying to replace the two supercharger idler pulleys (one smooth and one grooved) and the entire supercharger tensioner subassembly on a stock 1998 Grand Prix GTP. I purchased the correct parts, and a T50 bit and an E8 bit. I think the T50 is really supposed to be a T47, not sure if that makes a big difference. My first question: for each of those bolts, are they reverse or normal threaded? The E8 bolt seems like it's going to sheer off. Second question: the bottom smooth tensioner is very difficult to get at. A rachet with the torx bit on it is a bit too long to fit between the bolt and the inner fender. How can I get to this? I prefer to buy the right tools for each job if they exist. Thanks!
