I am finally at the point of installing the exhaust system on My 74 Commando 850 Interstate I seem to be baffled as to how the hanger brackets got together with the isolastics and foot pegs . Can anyone give me some guidance and or a picture of what the mounting brackets look like together I have the service manual and parts book but the brackets they show don't look like the brackets I have.
Thx

Which particular "Interstate" mufflers? 'Cigar' or 'annular discharge' (bean can/black cap)?
 
Which silencers are you fitting, black cap or pea shooter as the brackets are different.
 
This is what it looks like with peashooters.

wow guys great pictures they are the non pea shooter type I would say cigar shaped
 
So my brackets are all triangular in shape which is what the manual shows more like the first picture The second picture has a rectangular one that doesn't appear like mine?
Thx

The second drawing on the Andover site (I assume you are referring to this?) is the peashooter exhaust setup.

Which ones are the ones you have? Like 9, 10, 12(x2) also 23(x2) on the Andover site? If so these are right, and look at the lower pic I posted above - with the red arrow on it.

Note that the 12 and 23 brackets go on the same way for both types of exhaust, which you can see better in my top picture - it is just the large plate that is different.

They are not exactly drawn correctly in either the manual or the parts diagram, however, the assembly can only be fitted together one way.
 
These are the silencer/muffler brackets so are the two outer brackets that attach to the muffler by the two holes in the plate which are closest together.

Inner plate. The three 3/8" holes are the Z-plate passenger mounting holes and the two 5/16" holes are for the AV mounts.
