Thanks everyone for all the FABULOUS info. I pick the van up next Saturday. Once I have it in my hands, I'll compare it to the info given and go from there. The current owner has had it for 20+ years and drives it often for errands and fun. I believe he has the original wheels and he mentioned that it was really difficult to find tires which fits in with the info from Hotrod Lincoln. Does anyone know if the 1958 commercial 235 6 cylinder is different than the light truck and car 235 6 cylinder?
