What are the chances of picking up an 85-91 or 78-79 front ford 60 out at that yard?
Probably pretty good at Pick-Your part, there was at least ten rows of trucks, the vast majority of which were Fords and most of those in and around those year ranges. Worth two bucks to go take a look.
Also check the Ecology domestic yard across the street and the Ecology mixed yard up by Brown Field.
But, if you don't find what you're after you have to keep going back, the inventory changes constantly. During our last trip they replaced two complete rows of trucks alone with new stock. Also, Pick Your Part usually has at least two rows of RV/motorhomes and large vans, some big ol axles under those things,,
