I have a gear drive on a SBC, it's one of those low cost eBay jobs. I had to cut down the button, not a good move! How do you know what length to get? The button I had the timing kicked out about 1/4" or so. So now I no cutting down a roller button doesn't work. Someone please tell the easiest way to get this done and don't beat me up......too bad!
Thanks Jim
