I am checking interest in repro 904 main shafts. I think I can get them either made or made out of 901 shafts for much less than the $1800-2000 that they are commanding now.

Nice! The only thing is that the swapable 2nd gears are internally splined differently than 3-5. If using 3-5 gears in 2nd gear, one's 2nd gear would be pretty colossal compared to stock F, GA, or H. I may not be understanding something with what you are doing.

There are certain ratios from 4 speed 901s, like HB and I, that are 2nd gear ratios, but sit in the the third gear position in a 5 speed. Remember that 1st in a 901 4 speed is the fixed mainshaft gear, so a HB or I second gear from a 4 speed has the larger splines. The 4 speed versions of these gearsets may also be easier and cheaper to get than real 904 gearsets. I like Chris's idea (IMG:style_emoticons/default/smile.gif)
