Read a thread on the Crosman Airgun Forum saying that a 1322 Valve has a "Length of brass body = 2.625"

The diameter is exactly the same as a 760 valve. I did not measure the 760 valve (like an idiot) when I had it out and I dod not take the valve out of the 1322. What is the difference? Is the 1322 valve longer? Can they be swapped out?

Thanks
