[Roadsters] Alternator Mounting Bolt Sheared

[Gary and Cindy Ault]

Bob,

I didn't know Nissan made the smog pump mounts in aluminum.  The mount
from my '69 salvage motor is cast iron.

Is that the smog pump in the picture,
or an alternator?  In any event, It looks like you have the triangular piece;
You need the spacers which go on the 10mm bolts to the timing case.

Gary

I have the later
aluminum (smog pump?) bracket that mounts to the RHS of 
the block
that looks
like the part shown in the link, behind the mechanical fuel 
pump outlet
nipple:
