both skids that I'm working with are 121 inch so mine is a little more straight forward. The difference with mine are that the '97 skid has 11.5 inches of travel and rebuildable shocks

. The 95 was the butt pounding original low suspension with basically throwaway parts

I'm not too sure but putting in the longer track on yours would require a longer tunnel or an extension if it truely is a 136. good luck too you with your modding and let us know how it turns out
