I didn't know you could get different gears for the rear end. I been looking around and haven't found anything yet. Does that clark 5spd fit right in? like a direct replacement of that 4spd? or does it need different bell housing, mounts, relocated shifter, and diveshaft mods. I would think the 261 would get good gas milage but if it turing lower rpms, will it have enough power to pull a trailer at speeds?
Thanks
Jim
