I have a 318-340 tray & am using on a stock stroke 360. The mopar performance trays come with slotted holes & washers to use under main bolts. I would like to get the washer thickness so I can space my tray accordingly. I got burned on ebay by buying a "360" tray as advertised. So I am trying to make it work. Thanks, JP in the land of Oz.
