Shackle bolts reversed?
« on: February 10, 2019, 08:38:47 PM »
 
I've noticed my 67 LOS shackle bolts are installed opposite from what the AIM shows.
Has anyone else seen shackle bolts assembled reverse when compared to the AIM?
When I get around to restoring this car, do you think keeping the reverse installation the same (with a before picture to prove) to preserve its own unique assembly anomalies would get docked points?

your photo looks consistent with the AIM (at least as how I view it)....?

 Per the AIM the top nut goes towards the tank and the bottom away from the tank. The LOS is opposite.

I don't want to show my ignorance, but I've never let that stop me before, the picture I see matches the aim pic?

Mikes pic shows opposite from aim imo, as one is underneath car looking up. I remember our 68 matching aim but also it seemed correct for being able to remove a bolt in the future, i.e. tank interference.

  Chick,
  The nut mounting direction in the AIM is for the reason you stated. Maybe this was a line workers error or possibly GM did things slightly different in LOS. I decided to assemble it the same (wrong) way when the car gets restored. I'll have photos to show it before the restoration. When at all possible I want to keep the few flaws (re: small paint runs in the door jamb by the pinchweld & firewall cowl top area) and any others I come across during the pre-restoration documenting.
   I stumbled across the shackle mounting differences when I was installing new leaf springs in the convertible, and using the LOS car as a reference, had a heck of a time trying to get the upper bolt w/sleeve into the frame opening due to the fuel tank interference. That's when I looked in the AIM and discovered the difference.  I reversed the direction and the install went quickly.

Those shackle bolts were not that fun to get out to start with let alone in backwards!!

It is a  LOS Lefty' Coast thing. The California workers had a issues with verbatim compliance it would seem.
 My 68 (Van Nyes Car) had the same thing when I swapped out a Spectra Tank years ago.
The Photo is of the pass spring mount and the AIM is from the driver spring perspective.

Ponits? Not sure, better keep a photo in your glove box for the trophy hunt.
