for those with gloveboxes, seems that you could run a few long lines via the trans tunnel and put the heater in the trunk behind the seats, and offer some other ways to pipe in heat?
No not at all. I used to work on Lexus for a living and their larger SUVs often had a separate heater for the rear of the cabin. Never needed to work on one but could see the coolant lines running back from the engine area. They were well insulated in something like this stuff you can buy at HD or Lowes.Have you done this?

But they had the heater core near where they wanted to put the heat. The problem in an FFR is getting the heat to the front. I could see building the trans tunnel as usual and then adding maybe 1.5 inches on the top so you have a duct from the rear bulkhead toward the shifter where it splits in two. Then it gets tough. Most of us end up resting our right leg against the side of the foot box so your duct could drop down along the side of the trans tunnel between the front of the seat and lower firewall to the floor and be pointed forward. I got to say, all this just to have a glovebox? It will be a heck of a lot easier to do a normal heat/AC install and do a shelf or glove box in the rear bulkhead.
My first long-range road trip was 400+ miles in late October. The temp started at 45*, an hour later, mid 30's. Had layered my upper body, but the cold air was blowing in the cockpit and finding it's way up my pants legs. So yes my feet and ankles where freezing. Stopped at a gas station and got some rubber bands and wrapped around the bottoms of my pants, helped some. So count me as a person who's had cold feet in a roadster, but then I've driven in a hail storm too. :surprise:One person did mount the heater in the front of the trunk plumbed his air ducts into the cavity of the fiberglass vintage race seats. He cut outlet holes at the bottom front of the seats to exit the air into the low middle area of the cockpit. Pretty ingenious but those seats are relatively rare.
Question: Who has ever had their feet get too cold in a roadster?
Even though I have already stated my opinion about seat heaters, one other option that I will mention is the FFMetal firewall forward piece.
I think that it moves the firewall about 1.5 inches forward, but there might be other ways to get even move movement. At this time, I see no downside to doing this, and I would encourage you to get as much space behind the dash as possible. I would do it no matter what choices you will make for the heater.
The added benefit of moving from a .040 to a .090 thickness is also a good thing.
