After dressing up my last engine and buying $500 worth of pulleys and all new bolts my stock timing tab became an eye sore, i painted it silver and it looked much better but it would be nice if they were reproduced out of billet aluminum.
The one you have looks like it came from this site: http://fjperformanceinc.com/index.php?main_page=product_info&cPath=433_438_486&products_id=1013View attachment 246306 View attachment 246304
This one is metal that I got off of eBay. It's made for a Pontiac I think. It physically fits perfect. The numbers were way off compared to the Buick stock tab so I grinded them off and lined up zero and center punched it. Then I sanded and shot it with clear.
ATR use to sell a timing doctor sticker to put on the balancer. Someone was reproducing these and selling on eBay. It originally went all around the balancer but I cut mine where the critical spots are.
