Hey I have a 1940 Pontiac 2 door with a Chevy drive train 350 with a 350t trans and vdo gauges. This all came in the car when I bought it but the speedo was never hooked up I was wondering what need to do the job myself? I talked to a local speed shop and they wanted 300 buck to set it up for me. I was hoping to do it with a bit less invested. Theanks in advance for your help.
