Piper Saratoga Spars
 

I'm wondering if anyone has recently purchased spars for the PA32 Saratoga. We are having incredible difficulty in locating spars, let alone a price for a beautiful aircraft grounded due to corrosion. Allowable exfoliation seems to be around .010" after finishing via wet & dry, blending back to sound, parent metal.

I would appreciate any advice on sourcing these - thanks
