John, it is always good to have options, so here is another potential solution. Please note that this works for a mod-aircraft in it's own folder (not packaged in sfs file):
Please see my post on page 8. Although it refers to Avia B-534 mods, the technique should also apply to the A-20 series, or any other aircraft with a similar configuration; that is, if there exists a wheel mod for that particular series of aircraft. Just replace my references to the Bk-534 and B-534 III, with your A-20N, and obtain the neccessary copies from Jero's A-20 wheel mod, to place into the appropriate A20N folder.
I can't guarentee this will work, but it's worth a try. Be sure to backup your A-20N files so you can revert if necessary.
Please let us know if and how you got it to work, as it may help others.
Thanks, and good luck ~ Rudi
btw; the strat's pick-guard is on the wrong side, Jimi played 'em left handed, but upside down.. just kidding John, it's a great pic. I think I've built one too many templates to be noticing stuff like this
EDIT: My apologies everyone. I totally forgot when I posted this, that my instructions are only applicable to the Avia B-534, as Jero had made it as such to allow display of the wheel hubs unique to each skin. Believe me, I had the best intentions, but my brain had a major malfunction on this one. Again, I apologize for any inconvenience I may have caused.
