Hey guys, I have a question regarding this topic since I will be doing a swap to a manual this winter. I keep hearing about a difference between the "chevy" throwout bearing vs. the "pontiac" bearing. Wouldn't whatever came with the clutch kit be correct? My thinking is that the clutch doesn't know what engine it is in, it is just bolted to a flywheel. It the input shaft on the transmissions (let's say a Muncie) is the same for a chevy or pontiac, where does the difference get accounted for? Are the bellhousings the same depth from trans mount surface to flywheel surface? If not the input shaft length would have to be accomodated somewhere, would the pilot bearing (bushing)be recesssed more form the flywheel surface on one vs. the other? Just trying to understand what might be different. Any insight would be appreciated.
