cab issues

[pontiacpro]

Does anyone know of anyone reproducing complete 67-72 cbs, or anywhere to purchase a rust free cab that is willing to ship it for a descent price. I started repairing the one from my 69 but it seems as if every panel I rmove i find more rot that i wasn't able to see before removal of the cab or previous panel. I thought it would only take a inner cowl pane, floor pan, cab corners and rockers. now i find half the a pillar besde the cowl lower toeboard where the vents are lower b pillar behind the rocker are all gone. so all i got is a good firewall and roof and some glass. If anyone can help me with finding a nice rust free cab i would greatly appreciate it. This project started out in recognition of my wifes late grand father and will greatly appreciated by her father and aunts.
