Mid 1970's White Fiberglass Tool Box
 

Hi all. Back in the mid 70's, my Dad bought a white fiberglass across bed tool box for his 72 Shorty K10. After he passed, I got the truck, but the box had no functioning locks and was pretty beat up and I stupidly took it to the dump. I know the pic isn't great, but in the mid 70's, there couldn't have been too many folks manufacturing these would there? Just looking to see if I can track down the manufacture and see what's still available from them. Any help would be greatly appreciated.
