I have also posted this in the Auburn Forum. If you need suspension strap material see information below
I found a source for the suspension straps, aka "Snubbers". It is Andy's Garage in Delaware, owned and operated by Andy Wise, an AACA award winning restorer, and Oakland Owner/Restorer and Oakland Club Technical Advisor.
He has the straps in the proper width for our Auburn (1-1/4") and also has the rivets. He makes these straps out of Kevlar, so they are extremely durable. I am putting his contact information below. Vic Fregonese
