Driver's side Heat Shield ex. gasket question.

273 4bbl. Just removed the engine and there was no exhaust gasket on the pass. side, but the heat shield gasket was on the driver side. Can I reuse that? I don't see many repro ones, if any (see mention of NOS ones, rarely, when I do a search here). If they don't necessarily even need an ex. gasket, if i reuse the same one it should be good. if i do get a leak i suppose I can use a little sealant on the two sides of the thin metal... What have you guys done?
