Same in the power train. D-10 is narrower than the D-12.

Charlie, not to hijack my own thread, but do you happen to have a pic of your D17, so I can see what I probably wish mine looked like?

Charlie, I like yours too! Yep, I do wish mine looked like that.

And Nella, thanks for the spec sheets. One odd thing, the fuel tanks must be ever so slightly different. One holds 1/2 gal more.
