There are 2 rubber spacers that go on the M6 bolts holding the front valance near the wheel well.
The parts are NLA but does anyone know the thickness of those spacers?
Thanks.

There are rubber spacers for that?

These are the dimensions for the rubber spacers at each end of the stock steel rockers. I would assume they are the same size as the spacers used on the valences.

In inches:
.60" OD
.240 ID
.325" Height

In MM:
15.3 MM OD
6.10 MM ID
8.1 MM Height

* Since these are made of rubber all dimensions are approximate due to the compliance of the rubber.

Hope this helps!!

stack some 1/4" faucet washers. looks OEM works on the rear, too.

Perfect. Thanks.
I think that a piece of rubber hose will do the trick

Mt 73 had pieces of hose but it distorts and won't compress. If you can't find any pm me. I've got hundreds. IIRC you'll need to pass a 7/64 bit thru them to enlarge the #8 hole so the factory bolt can slide thru.

A number eight hole is bigger than the 4mm bolt that goes there .....................

The Cap'n

Your probably right John but I remembered losing my temper trying to squeeze the washers over the bolt threads so I enlarged them. The reason that I used a larger bit will become self evident once you try to drill rubber. Especially Buna-N type rubber. I suppose a small rat tailed file in a drill might work better. BTW, here is a pic of a #8x32 showing it's metric o.d. dimension. I didn't mic it but the nominal measurement displayed here should be acceptable, in that we are just "Jury Rigging", anyway.
