I wouldn't look to hard, for what they want you could build 10 of those damn bumpers... I emailed the address on the site, and this is the responce I got back
"Currently we produce these bumpers for late model Dodge, Chevy, etc. I really appreciate your comments about them. The cost is $3,000 for the front, and $2,000 for the real bumper in aluminum without a brush guard. Unfortunately I don't think they would fit your 1982."
