Very nice work. Yes when you do the install yourself you discover lots of horrors that you just wouldn't do yourself. Another area worth foam filling is the main bulkhead. The large circular holes leak into the cockpit, i filled this with closed cell foam and my cockpit stays quite cool. Other things i did include adjusting the nylon door triangular stops because they just didn't come close to fitting and banged like crazy when you go over a bump. I also shortened the front drop links. Also bear in mind if you fit the Quaiffe box you with need to enlarge the aperture in the chassis where the shift linkage emerges as the rod naturally wants to sit further back than the hole will allow. This is a real pain to do when the gearbox is fitted as mine need opening a good few inches. Also the rear body support frame clashes with the tail cone of the gearbox so needs cutting down. I also took apart the gear lever mechanism to reduce slop. I had some better spaced nylon pads machined up. Loads of other stuff i have done, im sure i will remember more!. Still trying to solve the problem of bad wheel bearings!
