i have been looking to remove some headers on this truck and after asking around a bit , i believe that 4 wheel drive is a slightly different desighn and # than a 2wheel . can anyone advise on the differences and the #s please so as to persue the correct ones . thanks

Not sure of the numbers off hand, but if they dump straight down they would be 4x4. 2wd angled back.

Here is what was on my small block 4x4 when I got it. Both sides say "RH" so I'm guessing you can swap left and right on a 4x4.

I coated them with Eastwoods exhaust coating when I built the 383 that is in there now. They don't look quite that good any more but they still look pretty good after 5 years or so.

You will need a "real" left if your alternator mounts on the manifold. The LH has the bosses for this and the RH doesn't.
