In short, no washers in the column to dash area ... but there are insulators in the billet aluminum "spacers" in the mounting hardware. There are three of these and if you don't check them for movement/rattle ... you may wish you had. There are two in front and one in rear. These "spacers" (there may be a more accurate term for these) slide into the mounting bracket that holds the column to the supports. On either side of these are very thin plastic pieces that prevent the spacers from rattling. When I disassembled my column and went through the process of restoring it, several of these crumbled. What I used to re-create them was a 1 gallon milk jug. It may sound funny, but I can't tell the difference once they are cut to shape and installed. Easy to shape and they hold the column tight.
Jen and I look forward to installing our lower dash shortly. I should have it done this evening.
