Thanks Guy.
You have no idea how long this project has been "stalled" and how often I thought about binning the entire thing and starting over with a more expensive Hasegawa or Academy F-86 kit but common sense and frugality prevailed since the kit was so cheap it would not be as great a loss if it does get binned while the same cannot be said for the more expensive Sabre kits.
I am still disappointed with the fact that I failed miserably to create the desired 20mm/30mm gun ports but thankfully I still have six more of the Monogram Sabres to work with and if I am feeling extra gullible I have two ESCI Sabre kits to bash if I need further abuse.
I forgot to mention in the OP that the ejection seat is getting swapped out for something more modern. My first choice was the Douglas ESCAPAC seat as used in some models of the A-7 Corsair, A-10, A-4, A-7, and other aircraft. I may still go with that choice but it all depends now on getting it to fit the cockpit. The other option is the ACES or NACES ejection seats used on the A-10, F-14, F-15, F-16 and F-18.
