I was changing the batter on the 65 and found this floating around in the battery tray.
It's shape looks slightly familiar...but I have no clue.

I'm thinking that's a retainer for the underhood insulation blanket. Looks like the center barb rusted off.

 

That looks like the plate that retains the gas pedal linkage to the pivot under the dash. If it is that part, its a long way from where it should be.

 

It's also a long way from 1968 (the first year Olds used a cable accelerator pedal) if the OP's car is a 1965. Note that the plate has four holes, two for screws and two for the locating pins.

 

Yeah...this made me chuckle

 

Looks more like updoc to me.

 

I know Joe is the king of all Olds parts application, but the 67 F85 with a six cylinder engine also used a cable accelerator.

 

Still not a 1965.

Also, the 66-67 L6 cable throttle setup does not use the 68-72 style accelerator that I posted above and does not use that square plate that was being discussed.

 

Joe, this is what you posted. 1968 (the first year Olds used a cable accelerator pedal) This is what I based my post on.

 

Ed,

I'm not arguing and I appreciate you pointing that out. My point was that the 66-67 cable throttle systems didn't use the square plate in the accelerator pedal mount that was being referred to until the 1968 model year. I could have been clearer about that.

 

I forgot the earlier cars used the throttle linkage. I knew the later cars with the plate held the throttle pedal in place by 2 screws, slipped my mind about the 2 alignment holes.
