So I'm swapping a 454 in the place of a 4.3 in an 89 shortbed. The truck is a 5 speed truck with the slave cylinder on the passenger side of the transmission. Now that I have the engine and transmission in place, I'm looking to get a header in this truck. I can't seem to find a header that any parts suppliers know for sure work. I'm sure someone has done this before. Please help. Thanks in advance.
