I see other members have covered you on the latch issue, but I would like to give you my experience with the door latches on my 1949 3100 series 1/2 ton truck. Purchased new latches from Goodmark Industies. Thought I would beat the odds and get latches that worked. NOT!! Had to return them. Neither of them worked properly. Fopund a set of NOS (new old stock) latches on E-Bay and paid the price. Both of the NOS latches worked beautifully!!
