Thanks for the suggestions. I had used drinking cups for the wheel wells on the Intro, and that did work pretty good.
As far as shimming the retract, I played with that, then decided against it. Right now the retract is nice and flush with the lower skin. It would take a fairly thick shim to get a up-and-locked condition, and this would make the retract noticably "un-flush" with the lower skin.
Maybe the Sprint well covers would work. I think I'll look into this.
Man I hate to whine, but crap like this is why I HATE building (yeah, I know, ARF's aren't really "building"). It's such a waste of time screwing with PITA stuff like this.
Ok, whine over...I feel better now
