Hey guys, I have found a brand new header being sold by a local private party that the seller says "was purchased to go in my late-80s 2.6 liter ram 50" He crashed the truck and has this NOS part sitting around.

No item number, no marking on it to indicate manufacturer or part number. Are the exhaust ports the same from the 2.6 to the 2.4 engine? I've got a 1991 2.4 Ram50 that it would be cool to put a header on.
