I am rebuilding a Classic Roadster Shelby Cobra AC kit car from the mid 90's. The car was only ran for 75 miles then damaged and stored away. I am going through it from bumper to bumper. It has a built up 460 that the block came out of a 70 Lincoln. The alternator is shot and I noticed it was a old style with the regulator on the fire wall. Should I replace it with the same or is there a better one that is a direct bolt up and has an internal regulator that is a simpler install? I appreciate any info.
