Roadster door latch busted

[40-A Twins]

Driver side door latch broke with the door closed. After disassembling the passenger side to look for an easy way to pop it open, the only choice was to chisel off the small swaged tab that holds the latch assembly together and pop it apart with a screwdriver. this worked out pretty well and the door finally opened. The actuator lever with square hole for the handle shaft broke off. Should I just buy another repro door latch or would an original be better ?
If anyone is wondering why the scorched primer in this area, well this door is a poorly made repro and the beltline upper contour did not match the body where the door overlaps. There was a gap big enough to stick my finger into at this corner so I heated it up and reshaped it with a hammer.
