The doors are next on the things left to do on the 4105 Cadillac and the 41 door latches, handles and hardware were not in good condition or missing parts. After trying to fix the original latches (that did not work) I decided to install after market latches.  After doing some research I found made in the USA Bear Claw door latches at Dakota Digital and bought a pair. I need 2 pair but only got one to make sure they would work in the space in the 41 doors.  The drivers door was marked and cut out where the old latch was.  The bare claw latch was tried in the cutout opening, and found that the glass channel was in the way.  The latch couldn't be removed with the window channel in the way, after the edge of the door was welded back into place.  The window channel was cut and a section removes where I could get a welder in.  I drilled and tapped the holes where the spot welds were at the bottom of the channel then made a tab with a drilled and tapped hole on one side
