After I read this posting it got me curious about T66 tracks on 105 Shermans so I started digging thru all the reference books I have.

In "Sherman: A History of the American Medium Tank" by R.P. Hunnicutt there's a couple of references to T66 tracks on these models. In the back of the book there are pages with nothing but detailed specs on each different model of Sherman. On page 547, the entire page is for "MEDIUM TANK M4A3(105) HVSS". There is listed: 'Tracks: Center Guide; T66, T80, and T84'. Earlier in this thick book, on page 271, is line drawings showing view from the side, top, front, and back of "Medium Tank M4(105) HVSS" and it is the EXACT picture of the Tamiya R/C Sherman except it has T66 tracks. And there are numerous pictures of Shermans with T66 tracks; a couple of dark pictures that show these tracks installed on a Sherman in the factory and it is hard to make out the gun mantle but it looks a LOT like a 105.

I'm been planning on ordering a set of T66 tracks for one of my Shermans so I can find out IF I like metal tracks. I feel comfortable that T66 tracks ARE correct for 105 Shermans.
