Well I started with an 8 and made it an 8+18" (CJ8 with 18 inches added just in fron of the roll bar behind the skid). But look at the spec sheet and start from BEHIND the skid mounts. If u use C-channel make sure you box it. the rest of the frame cannot have any rust that would weaken it, otherwise it should hand the HP no problem. If your still worried about where the motor mounts are, you can get the M.O.R.E. frame plates that go from the front bumper back to the first body mount. Use Urathane bushings on the tranny/t-case and you wll need to get/make a longer rear drive shaft.
