hey out there! I just got a 1987 b2600 4wd. It needs a complete exhaust system. Does anyone know were I can get a header to replace the original manifold. I can only find online headers for 1987 b2600 2wd, not for 4wd.
Also, some say that a d50 header will fit, is this true? if so what years fit. thanks for any help.

 

try ebay...i haveseen them on there
