Are upper rear a-arms different on each side? Is there a left and right? These are left over from my first Pantera (1971). I am cleaning out the garage and will be putting them on eBay.

If I recall correctly they are left and right handed for each side by way of a slight splay and indexing for the ball joint, plus the joining plate is slightly offset.

That's my eBay listing (blue a-arm). The two black units are going on eBay as well and I now know they are both left sided.
did you find/observe what made all them left?
It is exactly what Julian described. There is a slight splay at the bottom of the ball joint ring. I think it is intended to provide room for the ball joint boot.
My 1972 project car came to me completely disassembled. It came with three upper rear a-arms. One was the blue one on eBay (its right side counterpart is MIA). It also came with two newish looking a-arms in black that are slightly longer than its original blue a-arm. The newish ones also have a tube in lieu of the flat piece of metal as you can see in the picture below. I have refinished the newer a-arms in powder coat. It also looks like I may have the ball joints reversed in the new a-arms and may need to flip them over.

Those are likely an aftermarket vendor product to address camber with super wide modern tires.
That's what I was deducing, although I thought they are intended to remedy too much camber when the car is lowered.
From Precision ProFormance:
EXTENDED UPPER REAR A-ARM. These a-arms are made from 4130 Chromemoly tubing, and are extended 3/8" farther than the stock a-arm to improve camber. A necessity if your Pantera is lowered.
