Old Yeller

One question I have, I read somewhere that B body headers will fit these trucks, does anybody know if that is true?

All of the truck headers I can find are 1 5/8 tube, except some for Dakotas with 1 3/4 tubes. I wonder if They would fit?

I missed out on a set of W9 headers that were $75 on FB. The shape looked promising, and I am not opposed to making adapters.
Any header suggestions Budget friendly?, Help!!!!
Car headers fit fine on those old trucks, I put car headers on my old 69 D-100.
This will be the easiest header install you have ever done. Tons of room.
