Fuel sending unit

I own a 1977 Lincoln Mark V. It has the 460 CID engine and was made 5/77. I need a fuel sending unit and need help finding one. I have found one on the internet the fellow says was taken out of a 77 Mark (Part no: D4LF-9275-AA). The picture looks the same as the one which was in it but the Lincoln garage tells me it is for a Monarch. They tell me the part number for mine is D5A2-9275-A. However he also says the other one may work. Does anyone have any suggestions?

Thank You

Thanks for the info. I am restoring a 77 Mark V and this should help with a lot of questions I know I am going to have.
