Quick question on the MT bulk pack 1015 couplers. Do they come with the shims as well? Website doesn’t really say, and photo(s) don’t really show anything! Looking for a pack, or two, as I discovered they work great for body mounting, with shim, on the ConCor autoracks! Coupler height is just about perfect!! Want to convert the rest of my fleet to body mounts! Information, as always, much appreciated. Thanks.
