For sale is a set of 3.55 gears for the 741 case. Gears have some pitting from rust. I have used pitted gears myself in the past with good luck. I removed the old bearings and added some use usable bearings. So you can play with them at no much cost to you. Includes the spacer and shims it was set up with. $46.00 Free Shippinh in the USA.
