which header to use

TTI or Holley seem to be the only games in town. TTI fits great with a manual box. I don't think you'll get those for power steering. Have no experience with Holley. They look to be a shorty style deal. I tried a 2010/2011Jeep Grand Cherokee manifold with power box. No bueno. Fit great with manual box. The Jeep SRT manifolds are a no go. I have a set that I tried. They could possibly be MADE to work. It would take cutting, angling, and rewelding. I wonder how a smaller Borgeson box would work? I have no experience with those either. All my test fitting was done with a 73 Scamp.
