        5 1988 GT - happy

        1st build

        hahaa. the time it took to install the locks ? does that include the time i took staring at the after the quick arrival of my order. the fear set into what i was about to do, i mean really i could only go so far on the stock heads fully assembled in the old condition. so after the port and polish seating of the valves and countless hours of mind tripping wondering if i was doing it right for that matter doing the right thing by refurbishing stock heads. the triple springs, caps and locks went in smooth. only two got away from me and shot across the room. for me great experience
