[big gear head]

I've been working on my uncle's '69 390 hp 427 4 speed Corvette for a few weeks now and it's almost finished. One of the problems that he has been having for many years is the tach cable. Seems that it keeps breaking because of the angle of the cable coming out of the distributor. It's pointed almost directly at the firewall. He installed a 90 degree gear box on it which moved it too far and it's still breaking. I was wondering what the orientation of the distributor is supposed to be. Seems to me like it's not installed in the correct position.

Also, should this car have the 7029201 Q Jet carburetor or should it have something else? It has a 7040202 on it right now and I know that is not correct.
