Question on different models when ordering the proper digitizer?

I am interested in knowing which digitizer I need to order for a Samsung Galaxy Tab 3 7"? The model is SM-T217T .... When looking on Ebay, all I can find is SM-T210R for $`5-$20. I look up the T217T model and it's $60+. Will the 210 model work on the 217? Also it states in most "This comes with NO SPEAKER HOLE" .... I do not have the tablet, it's a customers and I am unsure what if it has a "speaker hole" or not. Looking at the 217 model, I do not see one, but I am unsure.

I want to order the proper screen.

Any help would be GREATLY appreciated!
