Sorry hemiviper588, I brainfarted and forgot these were your personal items when I replied last. I hope you don't feel slighted, as I had no ill intent.
As I stated there, I see nothing that causes me to doubt you. I would be willing to gamble on one, probably the right, as being correct for my cars. I also don't feel an overwhelming sense of need so that is likely the one 75LandYacht needs. I think the one on the left would fit too and don't know for certain which is correct.
As to testing, something with a motor that can be tested in 30 seconds with a set of jumper wires should always be tested IMO. Taking your word for that wouldn't be a problem either... I am sure nobody wants to deal with a non functional issue down the road. At the age of them, if they work today is the best anyone could ask for... as Ross said there is a known fix for the mast, but it is fair to know about issues ahead of time.
Thank you for offering them.
