They seem to be good on their prices. I noticed that most if not all the metal is from AMD. I did a little comparing and found that AMD has just a few things a little cheaper than Autobody Specialties. You could possibly use that to your advantage I would think since they are getting it from AMD. I have visited AMD here in Buford, Ga a few times and they have always been really good folks to deal with.
Just a comparison:
Deck Filler Support from Autobody
LOWER CORNER OF THE DECK FILLER.
FITS: 1967-76 DART SWINGER
FITS: 1971-76 PLYMOUTH SCAMP
$34.00
Same part from AMD
$32.95
Not a big savings but a little goes a long way.
Just my two cents.
