Hello everyone! I'm a bit of a novice and would appreciate any help. I noticed my 79' FJ40 Fresh air smelled like it was pulling its air directly from the engine bay (and it is!). I have approximately a 1/4" gap between my heater blower and external vent on the car. What's the proper way to seal this? In some images and threads on the forum it looks like I'm missing a piece, or shroud or gasket of some sort. However, looking at my Haynes repair manual...there doesn't seem to be any piece there? I'm trying to figure out what was originally there instead of trying to stuff something random in the gap to close it.

You need to use something gas fume and heat resistant. Measure your gap. Use like wax papered cardboard to make a frame inside and out the right height/thickness + say 1/8" and size of the perimeter - fill it with 100% silicon, let it cure.
Just looked at my 72 that the heater has never been off as far as I know since 82. It has like a thin sheet metal plate oversize cover plate, might be some gasket or foam on the inside

I'm sure this subject has come up b4. You might search.
Hard to get a good pic. Where the sheet metal tab is its tight the other side near the firewall appears to be a 1/8 gap shining a light up threw the vents. Maybe some finger applied silicon calk or perhaps I can work some gorilla tape around the perimeter.
This is the blower off of my jan '72. It had some form of foam gasket. I can't seem to find these foam pieces or rubber gaskets on the microfiche set I got from a local Toyota dealer in the early eighties. The set shows a lot of body rubber and loads of other gaskets and such. Maybe one of the real old timers has access to additional info. I believe SOR carries some form of generic foam gasket refurbished kit for the blower and heater units.
Can you get any adjustment to blower position out of the four mounting bolts?

Yeah this is gap
sadly. this is the gap i have with the blower pushed over as far as i can get it
I am rebuilding a heating system for an FJ40 and bought this set of foam gaskets about 6 months ago… have not opened it yet to see exactly what is in there but check this out…. A bit pricey but in my disassembly and cleaning of the old heater box and blower, this set seems to be complete.

That does look like a pricy complete kit..
OP if you can loosen the heater to make the gap bigger - it will be much easier to install a closed cell foam gasket, then slide the heater back over for that crush fit. I had an blue counterfeit Ensolite closed cell foam backpacking pad 1/2" thick that I made tons of spacer/dampers/vibration isolators for all kinds of stuff
