I don't think anyone makes a hi-perf. balancer with the marks on the pass. side. With today's poor QC at most manufacturers, you can't trust their markings anyway. I just found TDC, and put a timing tape on the one I bought a few years ago, which was supposedly for a pre-'70 340. Sorry can't recall the brand name... could be the generic one that Summit sells. Markings were way off.
