I once got a top cover from Sarco that had a coil spring and ball detent for the latch (or am I dreaming??????????) It was missing something so I sent it back for an exchange but got a refund instead as they claimed to be out of stock (???). At a recent shoot (we entertained Toyota engineers), the top cover latch on the 1919 that was there was real tough to open (as is mine). If I am on the right track here, anyone know where I can get one of these???? Otherwise square me away from my state of confusion................
