Now on my ZR4 since it is running rear wheel drive I think the guy who did it pulled the shaft out that the speedo pick up runs off. Is there a way around this to make the speedo work when running RWD or does it run off the front axles? Anyone that has pulled one of these gearboxes apart and made to run RWD only will probably be able to answer this for me /ubbthreads/images/graemlins/laugh.gif.
