Header fitment (W2)

[T-Fish]

Hey guys. I don't know if anybody on here would know the answer, but I'm trying to find out which headers would fit on a 1978 D100 truck. The headers I currently have look to be for an A-body, but I can't confirm this. I'm aware that there are companies that make headers specifically for the D-series trucks, but there's a minor catch: I will be using W2 heads. The companies that make the truck headers don't make them with the W2 bolt pattern. I called TTI with hopes that they would know (TTI is what I would prefer to buy) and they had no clue which headers they make, if any, would fit my application.

Thanks for any and all help.

Buy any header you want and weld W2 flanges to them. I bought my W2 flanges from Schoenfeld headers.

Ya, your probably going to have to do a bit of custom fitting. This guy has some nice flanges for a good price.

Buy a truck header because they need to hang lower to clear the floor board. Any cheap set will work and then do as suggested above, weld on the W2 flanges.
