The CVOA sells a heater box kit that includes new foam and some gaskets. I bought one online, maybe ebay, a few years ago. Not very expensive. I used it on a 72 Vega with a 73 heater box. The 72 box was metal, the 73 I think was plastic.
The only Vega's that only had a little rust were the ones still on the assembly line.
