Hey Dave
Unless I am way out in left field,,,my cab and this cab are for the most part the same cab and both are 1/25th scale. The cab I am casting now is one of the cabs in this post reworked by the man who made the master for it,,,he made it back in 2003 I think, this is prolly one that Bobby Griffen cast a few years back. The diff in the cab I am casting and this cab is the doors were cut out and 377 kit doors grafted in, the baggage doors, sleeper vents, cab steps rewoked and the leading edge of the roof was reworked and sloped off more like the 1:1 trucks. But I would think they are the same scale, mine is 110mm front to back, thats 110 inch in scale and I would bet the cab here is the same,,,
