FYI Folks,
This may be common knowledge, but if not I thought I'd share the following....
I was needing a good rear apron for my project and kept running into really poor condition ones or having to settle for an apron for newer cars that needed work and didn't look correct (no "H" pattern). I stumbled onto a site that referenced "Auto Craft Engineering" in jolly ole England. They make a completely new apron that is correct and has the proper latch. I will admit it isn't cheap at $251 US dollars (I also paid $115 UPS shipping), for a total of $371. But I think you get what you pay for.
I've attached a couple of pics so you can see the quality....

Hey Bill , good to hear from you .. Thanks for sharing.
