Will the sure grip 742 unit I have work in a 741 case?

look in the for sale section and you will see average pricing. i myself think the whole 742 carrier with suregrip and gears is worth around 4 to 5 bills. Some fetch more but thats aproximate value. Myself I would buy the desired gear and install it in the stronger 742 then sell the removed gears and the 741 carrier.Where in fl are you? I lived in Ocoee for years. moved in 1980
