Here ya go: $119,000 AED which is roughly US: $35,937.44
Of course you have tax and fees importation ETC....
All you have to do is buy it, dismantle it, cut the frame and bring it back in to US to a friendly DMV as a "kit" truck and hope no one digs any further into your little venture, and make sure not to have a wreck.
I'm way to risk adverse for something like that. Personally in a nasty car wreck, you can really run into issues with even "kit" style cars/conversions etc if an insurance company wanted to be really nasty. Say your 79 titled as an 80 series runs though a busload of orphans with kittens on their first trip to seaworld from money they saved by hard manual labor in the salt mines. Their fault, but hard to prove. If it's a big payout, you can bet mr insurance company is going to take tons of lawyers/forensics to dig through to find ANYTHING to make you liable. They find out some swap happened, watch out...it's even possible your insurance company may not protect you if it's not 100% squeaky clean on your policy about what you actually had...plausible deniability.
I have no idea the odds of you running over a busload of orphans with kittens on their way to seaworld, but just something to make sure it's all good!
On more serious note...
If I wanted a 79 setup, I would be contacting @SNLC @c2dfj45
@Eco 45 @joekatana and have one built from a 75 then secondly an 80 series swap.
