Hi: After checking the archieves, I decided to ask if anyone has tried the billet tab yet (with the built-in light) that's made by Proform. If so, what do you think? Is the billet tab worth the $87 plus handling? It seems very tempting because it's really tough to get my timing light at just the right angle (through the belts & alternator) to flash the balancer mark. Comments would be appreciated!
