[Roadsters] Alternator Mounting Bolt Sheared

[RWM]

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.
