Door slam plate

[peterg]

Had a lovely afternoon at Epsom. It was quite weird. There were five 403's and only one 401 that was exiled to the other side of the lawn because the 403s had filled the allotted space.

I think my problem was caused by the door cable tightening. After the wedding I fixed the window and the door was OK but driving back after about 15 miles the door suddenly started opening. I could hear it click twice and then open. I fixed it by loosening the cable at a garage (no tools on the car).

Anyway, the plate has fractured, so the question for me is what metal would it be best to cast the replacement in?
