can anyone help me on what to do about getting a block off plate to cover the a/c hole in the firewall.Im going to pull the engine this fall and paint the engine comp.so I thought It would be a good time to get rid of that condenser box.Is there a plate out there that I can buy or any good ideas.?I go to car shows with It so I want somthing thats going to look nice. thanks.

The one from Spotts Performance seems to only fit non-A/C cars.

However this one from Detroit Speed and Engineering might be the correct one. You may have to call them:

DSE Firewall FIll Plate

I pulled my A/C suitcase last summer. I then layed the suitcase, firewall side down, on a piece of sheet metal. I drew around it with a Sharpie and marked the bolt holes. I used a pair of tin snips to cut it out and presto, custom A/C hole cover. I used some caulk on the firwall just outside of each big hole. After a little massaging to get it right it really doesn't look half bad. When I pull the engine I will most likely scuff it a little and paint it with the rest of the engine bay. It's not factory but hey, it didn't hardly cost me anything.

They regularly have AC delete plates on e-bay. With those, I'm assuming you can still use the heater.

The "A/C Delete" plates are nothing more than non-A/C heater blower boxes and will not fit a factory A/C car. The cut-outs on the firewall are different.

In my conversion of my '69 factory A/C to VintageAir, I cut a large sheet of 20-guage steel that covered all the old holes in the firewall and welded the plate on the inside of the firewall. I then went to the outside and completed the welding, and made a small plate to fill in the old blower motor hole in the fender well. Finally, when I am ready for primer/paint, I will complete the job by using seam sealer over all of my welds so they can't be seen.

You can see a pic of the work in progress here.

I have a ac box that is cut down and plated off, it looked good in the car. Im putting the air back in mine,, I can take pictures if you want to see it.

The DSE plate would probably be the best way to go. I decided to make and weld my own plates in. They are temporarily permanent and eventually I WILL install a DSE plate in mine.

I went down to the local HVAC (Heat,Vent Air conditioning) store and they built me one out of sheetmetal for free. All I used was silicon to hold it into place. Works like a charm.

Bob,

If the car was originally an A/C equipped car, the non-A/C heater blower box will not fit. The cut-out is different and the the holes where the heater core tubes come through the firewall will not line up.

Tom

The one you showed on e-bay WILL work. That is made for an AC car. The non-AC heater box will not work, but the one in the link will.

Non AC boxes have a "flat top" ie the top of the box comes straight across from the blower motor housing. Or the right side of the box would be rectangular. The one pictured will work. The shape on the right of the blower motor would cover the different AC hole in the Firewall.

all I did was grind the lip that sticks out on the firewall off and cut me a peice of aluminum a little bigger than the hole sealed it with silcone and placed it over the hole from the inside and screwed it in place, did the same for the round hole where the blower motor draws in the air from the cowl. painted it and it looks great to me. I can take pics if anyone is intrested

Yellowtail, I know if it were me.. after seeing how nice that piece is that Bob posted in the ebay link... I'd have to go that route! That makes it look factory! Man... it's about time Someone came up with a "better" fix!

Nice find Bob!
