Ive seen door handles ( inside and outside) as well as window cranks are available new online. I cant speak for the quality of them but just thought Id mention it in case its easier then having yours re-chromed. Noticed your rear window cranks look like they are ones used on the front windows. The rear windows use a shorter one. Sorry about your vent glass, happens to the best of us. Ive got a spare one in Jacksonville Florida unless you can find one closer. Keep up the good work, shes a beauty
