Chris, since since no one answered your requests for all the small stuff you're missing, your best bet is to call/e-mail one of the U.S. Pantera vendors who have parted out a Pantera similar to yours, and make a package deal. It also appears you don't have the extensive current listing of Pantera suppliers so send me a post off-line with your e-mail and I'll send you a pdf of all of them.
Most of the take-offs from wrecked cars are quite useable and often cost 1/4 (or less) than NOS, but you'll likely need to do some cleaning. Even that's not much of a problem since most of the shiny parts were stainless steel and buff up nicely. Shipping 'old, used car parts' to NZ will slide thru Customs less painfully than NOS, too.
Here are a few e-mail adresses of parts vendors that I know have scrapped Panteras right now:
larryS@panteraparts.com
steve@panterasbywilkinson.com
www.extremepanteras@hotmail.com
www.DRBProFormance.com
I'd heard that PI Motorsports was sold a month or so ago and Jerry Sackett is no longer operating it; dunno if anyone there is currently answering e-mails but you can also try www.pim.com, too. Good luck.
