Hello. Can anyone help me with a small problem. I need a diagram of a 3 speed shifter assembly for a Huffy Regatta. I needed to replace the cover for the shifter because it's broken and the cable slips out of place. So being the do it yourself kind of person I took the cover off and then the cable promptly came out of the slot and I can't figure out how to put it back in. I went to the library and looked through all of the repair books they have and I've been digging through the internet to no avail. The bike cost me nothing last year through my communities freecycle, everything else is in working order.
