Good info Andy, and ties in with what I've been able to find so far.
Leaving the bay doors open will work well Cory - the 'bulge', and the 'step' at the rear were only really noticeable when the doors were closed. If you decide to fit bulged doors, I think Mike Belcher (Belcher Bits), based in Canada, makes a resin set. I should have his e-mail address if you wan it?
