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.?Dating the Mod. Had to be @ 1998-2000.Now the GM alternator comes with a? pulley that takes a thin belt. So I used & modified my original TR4 pulley to the shaft of the Delco alternator.Then I measured to find a belt that would work with the Alternator mounting brackets.I first found a farm tractor belt & had mm markings, but replaced with THIS NAPA BELT?25-24379.I need to do some cleanup & repainting but I used a threaded rod? with washers/nuts for the alternator pivot into the original TR block bra
 cket on the bottom. 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 pulleySherman?If you want more pics, you have my cell 410-302-3930 & email.Sherman?Sent via the Samsung Galaxy S10, an AT&T 5G Evolution capable smartphone
