I have a 1985 350/400 out of a 2500 GMC. Running the stock exhaust manifolds with the A.I.R deleted. Also using the stock down pipes as the ole 2500 came factory with true duals. Like a dummy, I pitched the old donut exhaust gaskets on tear down and now I have no idea what size I need to put it back together. Purchased a pair from O'Really's and of course they aren't thick enough. Anyone have any suggestions?
