Any suggestions for a speedo adapter. Would like to use the factory speedo in my 68 Camaro. My trans has a Deadenbear tailshaft housing with no provision for speedo cable and all internal components are race parts. I'm asuming I can't put one on it. Thinking of maybe drive shaft sensor to convertor box then to cable? Any suggestions? Anything out there available that might work? Don't really want a digital speedo. All the dash is factory stock. Hoping to keep that look. Need speedo to run it on street. "It's The Law Here!" Crap!!!
