It was probably done many years ago.
I think his asking price for a 69 Formula S 340 that is rust free would not be too bad. Scrap the doghouse and the rest looks like just paint mods, except for the diapearing rear spoiler.
What would you pay for a 69 Formula S? could you buy this and convert back to normal for that amount?
I have seen many custom cars that were done in the late 60's thru early 80's and you have to ask, WHAT WHERE THEY THINKING?
A 427 68 Vette at the Mecum auction this past spring had camero tail lights, 68 dodge side marker lights, 4" chopped top on a T Top Vette, about the same headlights as the 69 Cuda in this thread, What the hell was this guy thinking
How much to convert it back is the big question, buy it make a real Formula S and give it a good paint job and have the advantage of an old show car that has been garaged and pampered instead of left out to rust to the ground
My 2 Cent
Oh I hate it too.
