In the process of gathering parts to build a externally balanced stroker motor from a 70 440 HP engine. I would like to find a SFI balancer that looks as close to a stock mopar one as possible. I need to find out if there is someone out there that offers one that I can use all of my factory pulleys, and have the crank pulley bolt on and line up without having to alter or modify the bolt holes or use shims to get proper belt alignment. What are you FAST guys doing for this?

Thanks!
