Shipping bigger car parts by air freight??

I dealt with DVAP as a walk in customer a few years back. I thought they were pretty decent to deal with . I was looking for a heater box to replace the busted fiberglass one in my Fairlane. Found one, a metal one to boot. Told me it would take a few hours to get to it, they had to haul the car up front and take it out. Told them I would pull it out where the car sat, price went from $65 to $10.
