Up pipes part numbers ??????
Are the early '99 7.3 up pipes the same as the OBS
The part number for the OBS
up pipe is F4TZ-6K854-A = 1818165C2 (Int'l)
The part number for the early '99 is F5TZ-6K854-A = 1816124C1 (Int'l)
The reason I'm asking is that 1818165C2 comes back to a cam shaft gear. The Int'l parts guy came up with 1816124C1.
Up to what date is the early '99?
The passenger up pipe is up to 12/8/98 which is F6TZ-6K854-A = 1824434C1 (Int'l). Would this fit the OBS
Buying the parts from Int'l is way cheaper than Ford.
