I was going to make it as light as possible for some kind of racing thing so I made it heater delete...grinded down the back seat brackets and painted the whole interior in bedliner to keep it from rusting.
The heater problem can be fixed by buying new parts and getting all the linkages hooked up.
I plan on going over the bedliner in spectrum. Even though the car audio will be limited (Just a 2 way active and 6" subs IB in the rear deck)...deadening any car seems to make it better to drive IMO.
That bracket is getting on my nerves as I am not sure how to fix it. In a perfect world, I could find a rear seat, cut it out and weld it in my car. But again, I will need a lot of help trying to do something like that.
I also have 97 Mustang seats mounted the the OEM seat brakets. I really like this as I hated the seats that went in the car. The back seat has been reupholstered in the same stuff...so it's pretty nice.
