> Hi again Jim. Years ago modified my TR4 to 60 amp (?) Standard Delco alternator. I MODIFIED THE ORIGINAL VOLTAGE REGULATOR BOX, Keeping the Box in place so it looks original.Can send you pics of the regulator changed inside. I did Document and shared with this list at the time. And a couple members made some comments. I also had a whole write up & pics on the web; but Comcast/ home.net didn't save my website when Comcast evolved ( no notifications) & all my jpegs were on floppy disks.

For the top bracket I can't remember if it was the original TR generator bracket or one I sourced from an old GM Mercruiser 260 engine. But that's the easy part. The key was the pulley & belt mod as I wanted to keep the TR4 original size crank pulley & water pump pulley
