Rear-end questions

Sorry to tell you Joe but you can't use gears from a 742 case in your 741 case and a 8-1/4 SG unit won't work either. No gears from any case style will interchange. There is 2 styles of sure-grip units for the 8-3/4 and either will work in any case though. Your probably better off looking for a complete unit allready set up. I've seen them go for $350-600 depending on condition and parts used in them. Recently a buddy of mine had a rebuilt one for sale with 3:23 gears (I think) and I think he wanted $500 for it. Don't know if he still has it or not. If your interested I can check. He does top quality work.
