I have undertaken the task of trying to fit a westy pop top to my van....
While the paint is drying id like to get some ideas on how to best line the thing up before I cut a giant hole in the roof

I am going for a method similar to this...

I will be making the frame myself and should have the profiles bent by tomorrow.
The main thing that is bothering me is getting the rear hinges and the latch in the correct places..
Has anyone does this DIY style that can give me any pointers?
Thanks in advance!
