Today I took the old tires and tubes off of the stock spoke wheels, and polished them up. Removed most of the rust from them, and then installed some new tubes and tires. I'm in need of a speedo drive. This is on the right side - I bought this one from Treats https://www.treatland.tv/VDO-style-speedometer-drive-gear-p/puch-vdo-speedo-drive.htm and it doesn't fit. The tabs are too wide, and the hole for the axle is about 2mm too big. It also feels very cheap and flimsy. Does anyone have a line on a good quality OEM unit?
