Direct connection or duck lip spoiler
Spoilers by Randy does not make a rear spoiler, only the fronts.
The Direct Connection “duck tail” spoiler is a rear spoiler. The F body spoiler won’t fit, and neither will the one for a Javelin. I have one for a Javelin because I was curious about it fitting and it’s not close.
The Direct Connection version was ABS and hasn’t been made in a decades. They’re pretty thin and prone to cracking, and generally sell for well over $200 if you can even find one.
MAS made what I think is the best fiberglass version, but they’re out of business as well. It’s very close in dimensions and shape to the DC version and the fiberglass work was decent.
CNS on eBay makes one. I don’t have this version, but I have another one from CNS and the fiberglass work is pretty rough. It’s workable, but it would take more than a little bodywork. Better than nothing but you’d better know how to work fiberglass.

Showcarsrob in Canada has had them for sale as well, although he doesn’t currently have any listed on eBay. His version is about a 1/4” shorter on the width compared to the DC or MAS version, so it leaves a little bit of trunk lid exposed on the ends. It’s not a big difference and unless you compare it to a DC spoiler most folks wouldn’t notice. His fiberglass work is decent though, it’s probably the best version currently being made.
