Where to find a heater box replacement?

[1988blazer]

I had to replace my heater core earlier last year. I had to take off the heater box and when I did I noticed that one of the flaps and other miscellaneous things had broken on it. So I glued what I could back on it and replaced the heater core. Now my heater core is leaking again, and I want to replace the heater box too, but I can't find any stores that have the box. 1988 K5 blazer with heat and A/C

Wrecking yard or Craigslist. No store is selling that stuff new.

x2. my advice is to find an unmolested junker that has been sitting in a field or something that can be bought cheap, like $2-$300 and buy the whole truck. Then you have lots of extra parts.
