Vic thanks for the reply! the part number from Sam is 67280 that's his part number which says it replaces part number 66811-41200! the case part number is 66811-41115, i bought an oil seal 09500-22358, a gasket 66905-41170, i have included pictures of the two gear boxes, the new and the old shaft as well as pics of the new and old shaft mating up to the sector shaft! There are no shims! the original upper and lower bearing were shot and i have new ones for those! the pics are in my profile thingy if you can look at them there since im having trouble figuring out how to get them on here! thanks again mark
