(J>>>I believe the early cars came with 21mm master cylinders, and the GT5-S was 23mm. (Somebody correct me if I'm wrong; I also vaguely remember that the 1971 cars had a different sized bore than the 1972-up cars, but the Ford parts book doesn't support that contention. So, forget that)<BR>(B

(J21mm is .82 inches, pretty close to .75.<BR>(B

(JMore to the point though, as a guy who has two cars with those internal hydraulic throwout bearings, I would strongly urge you to NOT switch. Plenty of modern cars have them, yes. It was a very trendy thing to do to a Pantera in the early 1990s when I converted mine. But history has not been kind to this modification, for when things eventually go wrong, they go wrong in a big way and it is a huge PIA to make it right again.<BR>(B

(JThere is absolutely no reason to stray away from a stock-style system with an external slave cylinder. That system gives you numerous options for OEM or aftermarket parts, different bore sizes to give greater or lesser throw, or pedal effort, and maintenance is, by comparison, childishly simple. Cost prices are also now down in the weeds too.<BR>(B

(JIt took almost 20 years for my unit to fail, and McLeod repaired it and upgraded it to the latest model, for free, which speaks highly of them as a company. I am a huge fan of their clutches and recommend them to anybody and everybody.<BR>(B

(J>>>They ground INTO the gas tank???? I doubt it. The shield is a multi-layer affair with asbestos in between; what you're probably seeing is the inner layer of the shield. At least, I hope so!<BR>(B
(J<BR>(B
(JThe tank can easily be moved outboard, and the shield can be malletized or moved for header clearance. So I'm not saying the genius who did that to your car was justified by any means!<BR>(B
