It may be worth contacting Drew at AED. It’s a very long shot, but I sold him a set of 17” Forgeline RS wheels about 12 years ago. Perhaps he knows who has them. I know th fronts were 9” or 9.5” and the rears 11”.
You probably already know this, but they made a few versions- one with a cover over the lugs (which looks dated nowadays) and one with exposed lugs. Mine were the covered version.
I have a set. I hand polished them, center caps could use more. No curb rash. 9 inch front, 11 inch rear. Rears were widened by weldcraft. I can take more pics if you would like. $1200. Located in Lansing MI. Email works better. [email protected]
