What is a circle??

Certainly not the shape of the Fiberglass body i got from Frank.

So it wasn't his fault,  he just got it from another builder long time ago.

I laid an Ali Dome Ring on top of it, seeing that it was far from being round. Here a pic with the Fiberglass dome:

Two Cuts beside the shoulder openings down some Inches with an air saw and an air disc grinder later, i could solve this problem...

 

With a strap belt all was towed together. 

Now some Special glue and some Fiberglass from the inside, plus some putty from the outside, some sanding here and there and this problem is history too!
