Well, called TM headers, they're built but not sure when they will be coated and back to ship?? Sometime maybe next week, well I wannted them before end of next week, but since chances look slim, I think im gonna bite the bullet and just install my stock manifolds and plan on putting cab on next wed, so I can get started with getting all my wiring straightened out and try to get it fired up, goal is to have it running a week from this Sunday. I can always switch headers later, or if seems fine like it is. wonder if the swap headers would work on my 98 Explorer I just bought?? I would bet they are close??
