I found the best way to address the current unfolding crisis was to totally isolate in the garage. For a minimum of 14 days. 

What a surprise - an Pantera requiring reassembly! 

After scrabbling through the parts compost heap I came across these two parts that I am struggling to see the purpose of.   

Any Ideas from the brains trust ?

As Adam wrote, the first one is the main part of the AC idler.  It looks like you are missing the pulley and the bearing.  The snap ring goes inside the  pulley and next to the bearing.  The pulley is a staggering $302 on Wilkinson's website.  One of my cars had the same issue with the pulley and bearing missing.  Only the bearing race remained on the shaft and the pulley was long gone.  But for $12 at Autozone an idler pulley can be purchased that gets the job done.  And it includes the bearing.  Here it is:

 Second part is a mystery to me but I suspect it may be part of the emergency brake system ? 

 2511 was converted to a line lock many decades ago so I have no visual knowledge of that system but that’s my two cents 

Larry

A wild guess is the second photos shows part of the key locking mechanism inside the door. The rod transfers motion from the rotating key to the door handle assembly.

 Having just recently assembled a completely bare door I can positively state that the second part is not part of the factory door lock mechanism

 One of us will eventually figure this out. See my above wild guess thinking it might be emergency brake.  I have now checked the parts manual and it does not look like it is a Pantera parking brake piece  

 Could it have come from an aftermarket cruise control?

Found the AC pulley outer hub and I think the item is definitely the idler. Thanks all for that guidance.

Regarding the second item , I have looked closely at the door mechanisms and it does not appear to be part of them, and there is no post market cruise control fitted.  

The second object does have a small R stamped on it which shows its handed . I had convinced myself it was part of the door opening mechanism  but I can not see any internals missing. 

Thanks for the extra info on the pulley Steve. The cost is staggering for an original pulley! I went down found the center shaft, dug out a new bearing I brought and then spent the next hour and a half looking for the pulley outer again. 

No pulley yet but the shop is allot tidier!! No doubt carefully put somewhere "safe".

wrong routing from the A/C V belt ?

Simon

I think the AC v-belt is routed correctly.  It is on the rear groove of crank pulley and the front groove of the rotary compressor.  This idler is pushing the belt up while the stock idler pushes it down.

it will create a problem you are trying to put the flat back of the belt into the V it will work but not for long.  then it move the pass seat remove the rear cover remove the engine cover  fix the belt then reassemble

I think I understand your concern.  It may not clear in the photo that the idler pulley is flat, not V.  Thus the flat surface of the idler pulley is pushing against the flat surface of the V belt.

Yes it can give a problem because the V belts are thick and are not designed to work this way.

now it must running into 2 different angles

 

If you look at the recent second item photos the last two photos are on a cm grid sheet which should give a pretty good indication of the dimensions of the item. 19 cm long or around 7 1/2 inches.
