After further investigation, you may be right and this is some type of homogenous plastic such as ABS. I thought it may be fiberglass because that's what replacements are made from. But, of course, lots has changed in 46 years.
The biggest crack is this one in the front of the fairing. I may...
Started removing plastic from the '78 LeMans. I'll have to make a determination if I can repair some of the cracks or if replacements are required. I have no experience fixing fiberglass so that may enter into the decision.
Here's a view with both openers in separate images. I have a total of three doors (see my avatar) with jackshaft openers on all of them. The 8500 (left image) in on one of my doors and the new 98022 (right image) is on another.

I couldn't find anyone who has built something like this so I had to wing it...
Re-attached an emblem on the door handle of the monthly driver. Attaching it took about 5 minutes but it took me about 3 months to get around to doing it. The story of my life.
