I just kept watching the jeep ads \
put ads in craigslist (use search tempest) to search as far as you want.
point to long story:
a guy in vermont had a old jeep with bad top but good rear hatch. sold it to me for $50 + shipping.
It worked out great
the plywood rear hatch that i had made looked like a piece of plywood that someone had tried to make a rear hatch out of.
good luck with the hunt!!!!!
