I've decided to brave the rocker panel replacement. Actually, I've decided to pay for someone else to. Should I replace the sound absorber/heater tube running between the inner and outer rocker panels? The passenger side has been peeled open and the tube looks okay. Stoddards sells the tube for $234.25 each. Should I spend $500 for two tubes that I don't know if I need? I was thinking of going a bit cheaper, like Aeroduct Sceet (www.aircraftspruce.com), if replacement was needed, or even wrapping the existing tube with a Sceet shell and some duct tape.

Does anyone know the original tube diameter? Anyone have any experience with a less than repair/replacement of the heater tube?

Thanks!
