outside looks good. Inside has some rust, not huge amount but there mostly occasionally along btm edge where factory seam is.
Let me get you some pix of the inside edge I'm talking about and you can decide if you want to make an offer. I'd just as soon pull the extensions, lites and all and just cut off the rest instead if drilling spot welds if that's ok with you. Shipping could get ugly. Do you go to Farmington Mn. in June? I can deliver but that's a long time off.
