Do you know if there is difference is between the 60-62 torsion bar and the 63-up? I've got a few sets of the 63-up in varying diameters. Also, I've got 2.73 gears for the 7.25 if you can' find the 2.9 set.

I found the torsion bars. The real differences are the diameter,the length and the size of the hex ends. Are the gears new? and what d toy want for them
