I'm looking through victoria british's catalog at the moment, and it seems as they sell almost any body panel you need except the rear hatch. Motorsports seems to be the same way....

Anyone know of a company that sells the rear hatch to our cars??

Your best bet is probably going to be Zbarn because of the shipping costs. Shipping a hatch is going to cost you the better part of $100. I have found Greyhound bus to be reasonable. http://zbarn.com/

You can get a used hatch for $75 plus shipping:
