Project car is 1932 Essex coupe hot rod. I have installed a complete 350 with 700r4 ( mechanical speedometer drive) and complete wiring harness/ ECM from donor truck which was my daily driver. Has any one taken the vss from stock speedometer and retrofitted to another mechanical speedometer ( 62 Studebaker lark) ? I am trying to avoid the expense of buying a JTR speed sensor 2prs adapter.

Any information would be much appreciated? I have not tried to open the back of the speedometer cluster yet.
