Thread pitch for exaust rubber mountings.

[The yaki]

Just tried to fit a peashooter , new from norton classifieds, however the mounting threads are M8 ??? Inserts required then. 5/16 unf ? Thanks in anticipation ! Roy.

Standard rubber mounts are 5/16 unf, if the silencer holes are M8 then you need M8 rubber mounts so look on ebay.

Just use M8 bolts between the plates and silencers. The rubber mounts fit between the inner and outer plates

Thanks for that. Will invest in some m8 mounts ! Who makes straight through peashooters with M8's ? Grief !! Roy.

Will invest in some m8 mounts !

Why, as Andy Higham said, the rubber mounts don't fit to the silencers, they fit between the plates and are fixed with nuts.

My peashooters, like all the others I have seen, have no threads, just holes (5/16 or M8 - same) in the plates - so you can choose the rubber mount you want.
...or am I missing something?

Looks like I've got a non standard set up for mounting. Fits/works perfectly but off which other model ?? Not the first thing that has been found ! It's certainly not on andovers drawings. Mine is a mk3, Cheers Roy.

What you appear to have there is (at least) two made-up brackets.
What you should have is this set although personally I prefer the RGM stainless kit.

As it's a Mk3 then it would have had mounting brackets for black caps originally.

The inner bracket could be a modified black cap bracket although I'm not sure.

I'll get an rgm kit methinks. Keep it for upcoming Scottish autumnal crap ! Stuck in 5/16th unf inserts to take stock bobbin and bolt. I had the same professional fitment of earlier sidepanels emerge ! The plates have the same chamfer all round and are fully well chromed. Why ? I'll never know. I'll put them on until dark arrives after September. Thanks for your info. Appreciated, Roy.
