right i've had the car a few months now and when i first got it the speedo bounced around alot, never really close to the accurate speed.

after removing the clocks, then the speedo cable, then the speedo drive i can still not get the thing to work at all! i can only think that the problem could lie in the gearbox in the form of a damaged nylon wheel that runs off the diff?

can anyone shed a little light on this for me as its now driving me crazy!! cheers.
