Cab windshield frame and pillars needed!
 

I have a 1970 Blazer which I have managed to get rust free except one place. The front windshield frame where the removable top bolts to the cab is cancer ridden!
Do any of my fellow enthusiasts have any recommendations on how to repair it? Blazer cabs are hard to come by and truck cabs are not the same but maybe somebody savvy with body repair has a solution or a company who makes this replacement part? Appreciate any feedback! Thanks!
