I used to have a 76 FJ55 that was a real chick magnet in a rusty pig sort of way, anyhow, it had a crank that fit thru the front apron into the main pulley and was awfully handy for finding TDC. What was this for originally? I see my 60 has the same hole but I don't see the crank anywhere. I BS'd a couple guys that I could crank start the truck but I really never knew what that crank was for.
