41 Chrysler
try the street rodding section on moparts,,
or a wanted add on the HAMB web site,,
or the 40s mopar site called P15 D24
if you locate one rhat appears to be in poor condition, i know a guy that covers them in stainless steel,,,,way cheaper then having it restored its pot metal and they pitt like mad,,
if its a street rod, you could always go to a VEE BUTT windshield and eliminate the center post,
