I've done a lot of reading, and the link below should answer ALL of your questions.
I think the main differences are the vinyl top and that in the '95 and '96 models the final drive ratio is different between the std. Fleetwood and the Brougham. It may have something to do with a towing package, but I'm not sure.
'93 and '94 have the same look, but the '93 doesn't have the LT1, and the '94 is missing a few extras like this "quiet cam" feature they added in '95 plus some extra sound deadening. Also, '95 was the first year they went with R-134a refrigerant in the A/C.
