Yeah, the patriot headers will probably work for the A.D. trucks,
but the Deco's are alot narrower(if that's even a word)there is NO room between the block and steering box.
The only options I could find; were to move the steering box back, dump the exhaust in front or use fenderwell headers.
For me, considering the money and labor I'll save, the fenderwell headers are the best option.
