Might plan on new frame brackets and straps. If one is rusted out, good chance the others aren't far behind.

Make sure the fill pipes on the new tanks match the size of your existing fill receptacles. IIRC - the earlier tanks had larger hoses. Possible some PO swapped in earlier parts.

Probably a silly question but it is a long bed?
