As for the old glue, yes I recall it was a bear. I spent some time with a wire brush on a drill to remove the worst of it, and some on the underside I just left in place as it didn't affect the fit. The leather is also a bit heavier and I think it may hide a few surface irregularities better than the vinyl. The downside was it was also a bit more difficult to work with on the real tight turns.

I'm about to start covering the cap trim around the cockpit, and the dash, but I have one more question about how you accomplished that task. The exterior of the cap pieces cleaned up pretty good and I have been able to get most of the big chunks out of the underside. The contact cement shouldn't be a problem with the thin layer that remains in spots.
From your photos I can see that you had very good results with stretching the covering over the caps, especially with the compound curves. The question is, did you use the contact cement (I'm assuming that is what you used. If not what sort of glue did you use?) over the entire surface of the exterior (visible) surface of the cap pieces as well as the interior to secure the tag ends of the covering? Since with contact cement you only have one shot to position the the covering without any wrinkles, it seems a bit tricky to take that approach. I was considering doing the cutting and getting a good dry fit and then gluing one inside edge first. Once that side is secure I envisioned applying the cement to the other interior side as well as the covering and after it has set up, getting a good stretch around the curves back to the inside. Sounds complicated when I reread this, but maybe you'll get the idea. In any case, I'd like to hear how you managed to get such a solid look to yours.
My "other" hobby is R/C model building and flying. Since I go for the kits rather than the ARFs I've had a good bit of experience with covering the airframes with Ultracote and fabric coverings. I've gotten good with the techniques for addressing the complex curves in this environment, but the contact cement approach is going to be a challenge. anything you could add would be appreciated.
