Hi - yes I've done very similar albeit with two extra stages -
On the cab interiors I file down the base of each to about half their thickness, also I remove about 0.5mm from the top of the back wall and trim a bit off of the locating tab. I fix these back in, securing them with Micro Kristal Klear, which is basically thick PVA.
For the engine room windows, I remove them and cut off the lower 'lip' which holds them in on the inside, this rests on cutouts in the chassis and I was finding it was stopping the body from sitting lower.
Here's some pics of one of my efforts, together with an as yet unaltered 37, hopefully showing the difference in height.
