You are going to love that seat. To me, those are the most comfortable seats for any truck. A touch on the firm side, but very comfortable. I've got one in my '55. It's a solid bench (not a 60/40) with cloth upholstery and a flip-down armrest. I have looked everywhere for another one like it, and have yet to see another one. I'm guessing that it was for a standard cab.

As far as the blockoff plates, as soon as I get my A/C stuff hung back on the firewall, I'll definitely sell them. I got them to keep the critters out while I'm doing my build. My cab is an A/C cab, there are are holes everywhere in the firewall.

You're making good progress!
