So I guess I'll need some donor 3spd linkage rods for my welding project

I'll have to post pics on how it's done. Don't you 3spd guys get sick of having 3rd gear in your lap? I know I do. I'm a big guy and will take all the leg room I can get. Just want to be able to have my knees straight up and down and not off to the side. In theory I think my idea will work. By extending the linkage rods you should be able to move your shifter handle up higher and still keep the same "throw length" in the shifting pattern.
