    Because Vintage Air sells the mock up simply based on Gen 2, Gen 4 etc non vehicle model specific with the out put duct configuration of your choice. You then have to order the brackets for your particular application. The brackets are based on holes being in your stock firewall that are now gone with the custom firewall unit and look like hell anyhow as they protrude all the way through. So you can either weld bolts (elevator bolts are a common choice) or use a different style bracket like Hotrod Dynamics sells.

    Can you post a picture of that HRD bracket you speak of? I looked around on their website, and I didn't see a bracket for mounting a VA unit.
    Dave, from the old neighborhood in Jersey!

    Go to their 55-56 Firewall area >installation photo gallery > word file named Installation.docx the pictures are in that file. They’re just simple brackets that could be easily made, I’d never really looked at them before as I’ve only done a 57. I’m sorry for some reason it won’t let me add the other pictures from my iPad and that’s all I have with me currently.

    Never knew of elevator bolts until I read this thread. Looks like they are a good solution. On mine I just used low grade hex head bolts - welded the head to the passenger side of the firewall. Same result.

    The VA brackets I have are just 18 gauge sheet metal. Easy to make custom ones like those, all you need is snips to cut to size, a vise to clamp for the bend, and a drill to make the holes. Real easy. The hard part is being sure where those fasteners go - but it's probably more forgiving than you first think.

    I learned of their existence from a heavy truck mechanic 25 years ago, they work great when replacing a wood trailer floor.

    This is what I used. I just plug-welded them in from the front of the firewall. Got them at a local ACE Hardware.

    If I need one or two Ace is an option, but Fastenal is a must for quantities.

    Lowes has them too, apparently they are more widely available than one might think. I find McMaster-Carr to be more price friendly than Fastenal, and I get the stuff by UPS ground in 2 days.

    Yep, I’ve bought them from my local Lowes several times.
