Well another day of 2 steps forward and one step back. I was able to get the cab back on the frame for the first time in over a year. (2 steps forward)
The headers were hitting the floor of the cab. (1 step back) So with a deep sigh, after thinking I had gotten the doug thorly headers to fit, I had to remove them for good. I figured I would try the stock manifolds since I had them, but they will not fit either. So I am going to try the hooker ceramic manifolds or another mid-length header. I'll get it figured out eventually. Just bummed about dropping $600 on headers that won't work and i now have to try and sell and will no doubt take a big hit.
After installing the cab I can now see the mods that need to be made to the trans tunnel. So a little chopping and re-welding is in order. Not too bad really. Just need to relocate the trans shift hole a couple inches.
More to come.
