I'd like to mention a third method. Wouldn't it be good idea to take the rear trunk lid for the curved regions of the roof ? It should have nearly the same shape as the roof.
If this would work, one could alternatively check the junkyards for properly shaped roofs of donorcars.

Hi Benno,

That might make a good start, but it is rare that a similar looking shape is actually contoured nearly as close as it first appears. Once clamped it may be low by an inch or more in some places.

"For those who dare to be cool, the roof does bow two ways but, I'm certain that a piece of guage metal bent as it is to the sides and forced to bend to the frame is not a big deal. The front to back hump is less than 1/2" and the metal will give easily with some clamps. The front corners will show the mosty stress but that can be cut and puttied as shown in the pic. The door edges can be first attached with the given hump and the roof then be cut to fit the shape. It is mostly an illusion which can be easily made if the builder has a little artistic insite and experience. This roof can be made with a flat light guage sheet if metal and the most basic of tools without a hitch or a kit."

Hi JPB,

Rolling it in one direction is the easy part of course, but getting true shape in it without classic stretching or shrinking would require a press die that developed tons of pressure.

Cutting and welding the corners is not the best way to make shape in them. Tuck shrinking will generate shape inboard in a controllable manner with tools as simple as a claw hammer...no welding. You gather up the edge metal in a little tent like shape and then hammer down over the top of the tent (tuck). The metal gets thicker on the edge. It is a metal shaping job, not a clamp and putty job...don't want to get top heavy (IMG:style_emoticons/default/smile.gif) Here is an album showing tuck shrinking if you are interested:
