The problem is these were all hand made cars and no two are similar. If you stare a pictures long enough, you’ll see a tail light maybe too low between left and right, headlight maybe a tad high, etc. Much like early Jags. As such, no hardtop will fit any other car other than the one it was made for. Now, we’re not talking drastic differences, but a slight gap and it’s rain city!
I have access to one, but yeah, they go for mint! Part of the fun of this project is making everything
