Pretty much what I did but with few alterantes. I made side panels rolled the reardeck ,made sides extend up roll bar so I could tie the top in easily.Then made top thats extra long front and rear.
I then made the rear one piece.Mines little different in its 6 point cage ,has flat across top not as rounded,back is more like rear of 63-67 vette. Its little longer and tapers to a point in rear with rounded sides. My rear deck little wider. Building for 2 chutes in case of influx of cash.
Guess I'll just sacrifice more aluminum to the race car gods.
