In Sticky's manual it says that an Indian GP200 gearbox has a "smaller 3rd to 4th gear jump than Italian GP200 but not built as strong.Good for clutch life"

the vijay super 150 mk1 gearbox would be better, 3rd is the same as the 200 box you already have but there is 1 tooth less on the 4th gear to make it easier to pull

Absolutely correct in every detail but if the BSSO Production Class have to use the Indian 'box, they seem to be 'up there' with Group Four using 'em, so can't be that 'weak' can they?

I have used an Indian gp 200 box in my sidecar for thousands of miles without problems.
