There is a M1070 cab on shapeways. I had the designer upsize it to 1:9.8 but it was going to cost too much for my budget. There is a 1/12 scale version on there.
Three piece cab. 1/12 scale is a reasonable cost.

I am building a 1/6 scale version of the M1070 using a 1/6 CXT Cab, Wraith and AX10 axles. I used some of your drawings to help me scale it out.
