Sheet metal for a/c delete?
 

Anyone have a pattern or design for cutting some sheet metal to cover up the hole left in the passenger foot well after a/c delete? Thanks.

Are you trying to fill in the trapezoid shaped hole?

use paper/cardboard and scissors. Trace onto your favorite material. You can use self tapping sheet metal screws to attach.

Yes, Grady. Jamie, just wondering if this is the same size for all pre-89 cars. My buddy, who bought that green one you saw at the Dulles swap meet last year, wants this and I need one too.

The early AC units were mostly dealer installed. I have seen so many hacked up holes to feed air to the blower unit/evaporator that there is no pattern. For example my 71 targa had AC and it had a nice round hole. dtw's 72 coupe had a cavernous hole with no particular shape. It looked like someone had too much fun with the aviation snips. Your SC may have a std pattern but I don't know. The only way to tell is to pull the pass. floor board and see if they look the same.

Paper and scissors will be the fastest way to make a template to cover it up.

On my 82 SC I traced the shape of the plastic vent that passes between the passenger compartment, and the smugglers box onto paper (including screw hole location). Then used that as a pattern to cut out some sheet aluminum I picked up at Lowe's using tin snips. Then I drilled the holes, and screwed it in using sheet metal screws.

AC Hole
 

When I removed the AC from my '72, there was a nice round hole into the passenger compartment from the smuggler's box. I went to Home Depot & bought a plastic sewer (?) pipe plug. It had a nut in the center you could tighten to expand a rubber seal around the outside of the plug. I painted it black & used it to seal the hole. If I decided to use the hole for something else later on, I could remove the plug. Never did, though.

Ditto for me. The metal sheet was 0.020" if I recall. I have some here at home but my calipers are at the office. (Now that I think about it, an electrical engineer with calipers spells about the same thing as a mechanical engineer with a DMM, trouble :D).

Additionally I also picked up some single-sided stick foam strip which I affixed around the perimeter of the trapezoidal cover for a slightly better air barrier.

Since it sits behind the floorboard there is not much to see. However I'd be more than happy to take pix if anyone is interested.

Rick, did you really take out your 993's AC? AZ summer’s not that bad or are you just better acclimated?

Might want to try the 993 forum, us early car guys don't know jack about 993s ;)

My preference is to use aluminum POP rivets instead of sheet metal screws. Slightly cleaner and tidier.
