@ mac67 - I took the heater out of my truck and cleaned it up. I was just going to put it back in sans restoration but would it be worth having it rebuilt, or just buy new guts to put in the old shell? I've done a little research and seen it done both ways but I thought I'd ask your opinion.
@ Spotbiltxo - I think that sounds like a great idea! The longer I look into it the more I'm convinced it will be 'just fine' to clear coat the metal under the hood, to prevent further rust/any problems, and leave the exterior with a little wax and/or linseed oil here & there. =)
