hey guys! I bought a harmonic balancer for my truck, which was a crate engine pulloff. However, it winds up it is a 12:00 timing tab position balancer, instead of a 2:00 position tab. I've looked all over ebay, Summit, Jegs etc and have seen no mention of an aftermarket bolt on type tab for a 12:00 timing position. I know they exist, my 80 had one stock, but it was spot welded to the timing chain cover, which I recently tossed () Any ideas where I can get one that is a bolt on type deal?
