I'm hoping maybe someone else around here has run the same combo and has played the speedometer gear game. I took the roadster out today for its first official shake down run... Aside from a short list of minor issues, it seemed to do pretty good... Has a slight shimmy at highway speeds, that i am HOPING is in the tire/wheel balancing... and the steering wheel is way off center when going down the road striaght, but other than that, it ran pretty nice.

Anyhow, one other problem is that my speedometer is way off... I have 285/60 15 rear tires, (radials ) just about 30" tall, and a TH350 trans... anyone happen to know what speedometer gear i need to get a relatively accurate speed reading? Right now it seems to be about 15-20mph on the slow side. I don't even care if its 100% accurate, would just like to get something closer than what i got, so my odometer is a little more accurate as well. Thanks in advance for any help or ideas. -JB
