Hi Mopar(ts) Lovers,

I'm currently rebuilding my a/c box. It was broken completely at the fresh air door. Rebuilt everything and I'm very satisfied so far, but need to know where exactly I have to drill the hole for the fresh air door helper spring. I've found the attached picture on DMT's instructions (got the new Foam Resto Kit from them) and noticed that I've found such a spring.
As the damage went through the hole, where it is hold in the box, I don't know where exactly I have to drill the hole now.

Can someone of you please measure it? I like to give the spring the right position, so that it can help as it was designed.

Many thanks
Thomas

I can't tell you exactly where it goes as it is not a totally exact science and I don't have my box out. What I can tell you is it helps a lot if you rivet a 1/16" piece of sheet metal on the outside of the box there to prevent the hole from ovaling out.

This is what happened on my Charger's box and the helper spring was getting stuck because of the ovaled hole. I mean, it just plastic so it's gonna happen. I riveted on the sheet metal, drilled it and ground a small circle around the hole for the spring to rotate in and that fixed it. If yours is broken here, you may consider doing this.

That spring gets under a good amount of tension and will pull itself through a glue repair pretty easily.

Just my two cents

Many thanks for enlighten me. I would see that in a couple years, otherwise.

Really good upgrade to the original box, I will do that definitely too.

Now let's find, where the hole goes, I think I will ask DMT directly.

I just make the foam pieces

I can see if I have pieces from an old E A/C heater box at the shop to get measurements from.

Hi Jim,

yeah, I got my foam pieces from you (DMT), and the pic above is from your foam resto guide. You delivered to CA last summer, when I was there. Just wrote an email to Loretta 1-2 days ago, as I have the email address from paypal.

Thanks for looking.

Could anyone measure it? Still not drilled, as I have to produce the metal, where the hole goes into...

TIA

Thank you so much man, hugs to you. That was the picture I was waiting for. I really appreciate it.

I will share it also at cc.com, as I asked the same question there. Such information is very useful and should be spread.

Thanks again.
Thomas

Stainless steel metal is ready to be riveted. Thanks again for the idea to solve a 1969 mistake.
