BTW...I drilled a small hole through the flap and attached a cotter pin to a length of cord that Islide through the flap once I have my cable length set. It prevents the hinge from moving to the open position. Also, on those old style Summits, sometimes that hinge gets sloppy fromuseage, so at the very least, check them out and make sure it fits sng when in the closed position. If not, get out your pliers and make sure it does.
Wonder why they ever went away from the hinged design?
