Did you have to make any modifications to the GPMs? Or were they a direct fit?
I found a guy on the bay that machines steel spur gears, and he made a replica of the FRN and Alum 68 tooth high speed spur. I figured I may as well snag one while’s the getting good, even if I have to sit on it a bit, before I finish acquiring the rest of the parts I need to complete the build.
I want a more bulletproof drive train, even though I know, that will be a lot of extra weight. Just need a punchier motor I guess. Or I could just get the GPM ring and bevel, then lock the diff w/ a block.
