Technical Difference between Model T and Model A wire rims?

I have a guy offering me some wire rims but he and I are not sure if they're Model A or Model T. I am hoping for Model T. Looking at pictures of each isn't helping me sort it out. Are there specific dimensions I could check?

Any help is appreciated.

Lug bole spacing is different. T wires are 5 x 5, A wires are 5 x 5 1/2.

 

Just what I needed to know! Thanks 25mercury!

Also the T center hub is smaller than the A. Sorry, no measurements.

 

The fastest way to tell is look at the hubs. The T has a pronounced 'cone' shape
