OK. . here's the deal. . i've decided on putting a 12 valve into the 98' instead of going back with a 24 valve. OK. . so now, who knows about this swap out. . what do i need to get off the 12 valve engine compartment to fit and adapt so that i will have a turn key motor? PCM?ECM?harness? if anyone has a clue i'd like to hear it. . thanks Greg
