I am getting ready to set up my FFR supplied heater. The heater is supplied by Vintage Air and looks like pretty good quality. My question is, has anyone changed the location of the heater? I am considering moving it closer to the passenger side; FFR suggests that it should be 6 5/16" away from the edge of the standard firewall. I have a Breeze Forward Firewall and I think I can move it about 3 or even 4 inches closer to the passenger door. Thoughts?

My reason for this is I am trying to have the engine bay as bare a possible, but I really want a heater. Has anyone done this? I've seen boxes made to push the unit outward, but I don't think I need that, even with a glove box.

Thanks for your info and pictures would be great too!
