takeuchi ts70r parts manual/ glass kit

Hello all I'm looking at buying a TS70R for my garden center but it does not have glass or heater in it, the dealer and tak is telling me I have to buy a compete cab because there designed different then the glass model. I feel this is a lie when I put both models side by side the encloses are the same, I found a older manual showing the glass as a add on kit I was hoping there is the same for the new ones
