    LOL, yeah, it's getting long! But there is a ton of good info in that thread.

    The pedal was cake! I used one of the bottom holes from the original pedal, and only had to add one hole up top, then I re-used the bolts that held the factory pedal on. I then cut both pedals off and welded the 85's pedal on to the 06's pedal. Looks factory, and feels just right on my foot.

    I'll post pics here too for those that didn't see it on 67-72chevytrucks.com.

    Thanks... Looks awesome, and doesnt look as bad as I had pictured in my mind. It looks like it came that way from the factory. Very nice. I know the guys on the other site are loving this build too. Have you ran in on E85 yet. I wont be running mine on E85 i've never seen a gas station here with it.

    I'm reading the build thread. I'm trying to decide what to do for a/c, headers and wire harness still. I think I'll just notch the frame a little bit and run fbody headers. Your engine bay looks amazing you should do this for a living.

    Using the 5.3's own AC compressor is possible, but you will need to notch the frame and do a little boxing work. We determined also that a 99-02 truck compressor with a flat manifold will work too with no frame notching.

    I used the truck manifolds with only a little notching on the passenger side. I opted not to use f-body manifolds because, well.... they are ugly compared to the truck manifolds. At least the truck manifolds are a mirror image from side to side. Plus I plan on having the coated at JetHot, that should look sweet.

    After doing this, I realize that I could have done the harness myself, it's really straight forward. On the other hand, I am glad I had someone else do the first one so I could see first hand what is done. The next ones will be done by me. I had Hannah and Jesse at Wait4Me Performance rework the harness and do the initial "canned tune", that was $360 including return shipping.

    Thanks for the good words! But I don't think I have the patience to do these for a living. But if time wasn't an issue, I wouldn't mind doing a couple of these on the side.
