there is a small wood shop in Niagara falls that can make the bits..Owner is Manfred.-excellent with wood.....used to be located near Marineland, in a very small commercial mall and maybe still is. Cant think of the name unfortunately..but was jus down the road from Niagara Awnings

I would think that the majority of rectangular hatches were the wood/canvas type vs the hard rubber type, used mostly on earlier models.

Do not compress the roof to fit the frame.

The inside cab frame is curved to fit, but the outside angle iron frame is not and will distort the roof and looks most unprofessional.

Make the wood spacers and do them properly, with the gaskets.. Perhaps ask at antique car restorers for the window sealing tape.. the type used was very wide, much wider than typical window sealing tape. You may have to substitute, ..possibly the thin cork gasket material in bulk, cut to fit.

i may have a hatch I could sell, Id have to check, but ask around as there are many collectors in southern ontario who could probably help.

I will also check back in my files to see if I kept the plans for reproduction of the wood bits...but this will take a while.
