76 CJ7 kind of. Had Marlin set up the gears for me in the amc rear and dana 30 front about 20yrs ago. Been running T18 granny, toyota transfer 4.7, and 4.11s on 37" IROK radials. In the process of full with 60s (if I can find a front), and another crawl box. Just picked up a set of 44 swampers I want to groove for the snow. Anyone have any questions? I know its not a toy, but it is a crawler and I believe I know how to drive it....lol.
