[Roadsters] Alternator Mounting Bolt Sheared

[Gary and Cindy Ault]

Bob,

If you're using a stock alternator, I believe the adjuster bars are
still available, at least from Rallye.  Reasonable price, as I recall.  May
not be listed on his website, but if you don't have his catalog, the P/Ns are
>  '67-1/2 2000: 117-07
>  '66 to '67-1/2 1600:  231-16

If you like, I can
send you a tracing of a factory triangular brace.  Send a mailing address.
Gary

No, Gary, that's
not my photo, it's one cadged from the Datsun2000.com 
website -- as
competitive intel!

My bracket is definitely aluminum. May not be for a smog
pump, of 
course, but looks just like the one in that photo.

I have the
through-bolt and spacersmocked-up, just need the blue 
triangular brace.

May
needa different offset on the curved adjuster bracket to clear 
various bosses
on the timing cover casting. Not sure about that yet.

- Bob
