Vintage air install questions/help - 70' Chevelle

[Nick.V70]

I am in the middle of a V/A install and have a couple questions to see if anyone has come across the same and what you decided to do.

70' Chevelle that is a Malibu that I am installing a SS dash and VA#671400-VUZ Gen IV








1. I am using for the time being to close the fire wall a BMR plate and after installing the plate I found that the V/A mounting bracket will be over lapping it. Not a bad issue but I was wounding what are most using if you are not smoothing/welding the fire wall hole closed? Also if you are smoothing it off are you guys just welding mounting studs to hang the V/A so the engine bay side of the fire wall stays nice a smooth?






2. So I found that one of the center dash vents off the V/A unit elbows directly into the center dash mount. I could cap it off and "T" the center 2 vents into just the one outlet that points to the drivers side. Or I could cut the dash mount and re-angle it to work? Anyone seen this before?




3. I know it is called SURE FIT, not DIRECT FIT......So I am guessing the best thing is to bend the mount to natch the car and just run self tappers to hold it?



4. On the OE pull vent it looks to me that this is not going to be used after this unit is installed? So no more air blowing down low or am I missing something here and something will hook up to maintain this later on the install? I read over it and looked and it doesn't look like they are used again.







Couple more over all pics on the install. So far not a bad install once the dash is out of the way. I have the new dash I am using mocked up to check the fit before I start mounting to make sure. Going to start back on it really early tomorrow to beat the heat out here, going to be 95 or hotter.

I'm in the process of doing this on my 69 Camaro with an already painted and smoothed firewall. I ended up making 2 kind of u-shaped brackets that the Vintage air unit sits down in. I made it out of 1/2" tubing which bent easily with a tubing bender and it has tabs on it that bolt to the nutserts in the case. It attaches to the little shelf at the top of the toe board. Then I made a bracket that reinforces the stock dash brace/speaker bracket and was able to go from there to the right a pillar with a straight piece of 1/2 square tubing. It has two tabs welded to it that are attached by the two upper bolts on the glove box side of the evaporator case. Will be a very secure mounting with no firewall intrusion.

Planning on finishing it up this weekend so no pics yet but will post some soon.

If I hadn't already painted and smoothed the firewall, some studs welded to it in the right places would have sure helped.

Thanks for the post. I think I may move to a few other areas of the car today and put some thought into what I will do before I start cutting things.

Hi guys I will be installing the VA system in my 69 Camaro after the firewall is done also I was wondering if you could put bolts welded to small pieces of sheet metal and use the paneladhesive to mount them to the fire wall inside it would allow you to put brackets anywhere you need them.
Erik I'll be watching for your post.

im getting ready to do the same.. that vent running into the frame looks suspicious but i think your solution would work.

Well after doing alittle searching and hearing people say it was pretty easy of a install I think I may have found my problem and will be calling V/A tomorrow to make sure or get what I am missing.

Long story short my problem is that when I purchased this kit I told the guy I ordered with that I was not sure what engine set up I was going to be running but wanted to get the unit in the car because i was working on the inside and I would get the rest later once I knew what I was doing in the engine area. Well it looks as I have the right Evaporator kit but it is just the generic kit and not the package that should have been ordered with the mounting hardware and other special brackets meant for the 70' Chevelle. After looking on line at the instructions for the "KIT" I see where things are not right. I purchased that BMR fire wall plate because I had opened the Evap box and seen there was nothing to close the wall so ordered it. I also purchased this kit separate because I didn't want the OE still control panel and git the billet knob set up. I am not missing much but enough that made things not look right and I am completely glad I posted and took a step back because I would have caused way more work for myself trying to make it work. ha-ha...good thing this was not my daily driver!!

Here is the install sheet I compared to what I had for my install sheet and see whats missing > http://www.vintageair.com/GenIV%20sy...evellewoac.pdf
