Cheapest way to get a frame mounted fairing onto an 87 FXR?

Any ideas? Don't want to buy an FXRT/P Replica for big money. Thinking about finding an older vetter fairing and seeing if I can try fixing that on myself or have brackets custom fabricated for it, but not sure how that'd work. I see these windjammers, liberators far cheaper on facebook than any other kind. I'd rather take my chances with that than a cheapo replica you could get for $3-500. As far as I know, any quality modern reproduction will run me over $1,000. No fork mounted fairings because of personal preference.

Honestly, I don't even need a fairing my upper body never gets tired on the highway, but I'd like to see what it's like. Only thing that gets me is the wind at my legs on long trips, I know some of these vetter fairings have lower fairings. There are also aftermarket covers that block wind from getting through your crashbars, but I'm running forwards w/ no crashbars.

Advice appreciated, even if it deviates away from the original question.
