Re: New tune for headers?
Like ScottyDoggs said 4 hours tops in the driveway. the front and crossover are a easy. The rear I just dropped the rear of the cradle. loosened the front cradle bolts to get a little more drop on the rear. just lower a little at a time so you don't break any lines. I believe I unbolted the rack and anti-sway bar just so I can move it around. Some long extensions and swivels. Air tools help but are not necessary. It can easily be done in the driveway.
Re: New tune for headers?
Yeah, definitely gonna DIY this. Just bought this 100-year old house by the beach and am planning to build a 24x30 garage this fall. The plan was to roll the GP in over the winter and do the oil pan (dented and leaking) and steering rack (leaking), so I'll just add the headers to the list. I'll drive the Suburban while work is underway, however long that takes. I like to go slow and take my time on these jobs, so I like having it a garage, if it has to sit for a week in between when I can work on it, no big deal. Our garage in Louisville was 26x26, had plenty of room to work and didn't have to rush anything.
Wasn't planning on buying headers right now, but a good deal popped up here in the FS section. Got to thinking it would nice to have them on sooner than later but not for that kind of coin.
Still have my projector retrofit kit in the box from TRS, I need to get that done too
