Well I guess part of the search is over!
Some people have said that the 86's are out of stock but I have found a VERIFIED source for 86's. Another post about trying to find 87's in the sab system got me thinking, and after making a few calls and emails to several different sab dealers I was able to find some 86's. All 4 sab dealers I called reported of a dealer source in Michigan having over 10 units of the 86's. They all called the source to verify and the source came back positive for at least the two I just purchased.
I was a bit skeptic at first when the dealers would not tell me the name of this "dealer source" but after all 4 independently said some were available from this source in Michigan, and after the place I ordered from got confirmation of their presence, I am inclined to believe and share this information.
Just call up a Sab dealer parts department and they should hook you up
FWIW, I payed a total of 250.19 for my set of springs shipped to my door.
I hope this helps some!
