Brett- please keep a copy of that ad. I think I have 2 sets of NOS foams out at Sobotka's (with the rest of my NOS parts collection) that I will need to sell..
I think I paid less than $10 each in the late 80's! My Buick NOS parts stash is getting more valuable!
Good to know. I have two sets that the original GM wrapping has disintegrated they have been sitting on the shelf so long.
I have an original pair that I took off my '70 GSX before I sold it in the mid 1990s. They are wrapped in plastic and look brand new. Maybe I'll hit the "Bay" with them.
