The Aires cockpit is going to be a royal enhancement to your 234 Joe. Especially with the sweet greenhouse canopy that will allow you see it all quite well. That's what I like about what you are doing as you will actually be able to see most of the fantastic detailing you are going to do. Bonus that you've got the resin cockpit to fit well without too much hassle. At least I'm crossing my fingers that that is the case as indicated by your test fitting.
P.S.- Despite a despotic and sometimes ill tempered moderator, your 234 would be a welcome sight over on the '46 GB.
