I need a speed sensor to run my 90 Tpi system with my th350 on a hot rod. I think its the 4000 pulses per mile but not 100% sure. I know I can order online just rather pick one up here if someone has a good one laying around that's no longer needed if not I will order somewhere online. If no one has one what's a good company to get one from. I can also be reached by text at 479-453-6094
