Lycanthrope, some of the yards have started posting lists of what has been recently added to their yards...Its not always accurate, but I think its a good point to start with. Also, I have decided to take a few photos with me to show at the entrance of the vehicles I am looking for. I hope that will save me time energy and money if they can tell me if they don't have any. I have yet to try this, but will probably get a chance in the coming week or two. I will reply here with my results after I try that approach.
'Max' 1964 Panel Wag 230/T90
