Hooker headers?
 

So I scored a good deal on a brand new STC soft top for my 1971 Blazer and the guy also had a set of brand new ceramic coated hooker headers 2452-1HKR. Well after I bought them I realized that part number is for a 2wd small block and I have a 4x4. So my question is does anyone know if these will still work on a 4x4 or is it a lost cause, I dont mind doing a bit of adjusting if thats the only difference?
