Are All Sportster Tanks Created Equal?

I am new to the Harley family after purchasing my 2014 Superlow 1200T so I have a question. I'm looking to buy a tank bib and all I see are a couple made by Mustang. I don't like the bra that Harley makes so I wanted to buy one of the bibs, but i can't find one specific for the 1200T. They make them for the 1200 custom and other Sportster models. So my question is are all 4.5 gallon Sportster 1200 tanks the same? Thanks
