@LicenseToGrill - Are you going for a true restore of just trying to make the grill usable? If you check your PM's I'm in Denver this week and brought the ash ring crossbar with me that I've been promising you. However, if you aren't able to find an older ash pan, you could always get the new ash ring and catcher and install that. It won't clip onto the legs like it would a new grill, but with a few easy modification options it works just fine. Also, since I have been in Denver, I have seen all kinds of crazy deals on grills. You might be able to pick up a grill with an older style ash catcher fairly cheap.
Here is the link to my ash catcher upgrade/modification. Mine is a permanent way of doing it. Some people are doing it in less permanent ways like using hose clamps or trimming the leg tabs so that the do clip in. FYI - I you look at the pics in my ash catcher mod, that is the cross bar I have for you, but it was soaked in CLR and is in much better shape than that picture makes it look.
