I had no problem with the tracks but I use a Tamiya side cutter to remove the links from the sprues and its very sharp and clean.
I did leave off the gear shift levers etc. I thought about leaving off the steering box, etc. but then I didn't want to add the little linkages after the fenders were in place. This kit has the armored cab and it is easy (so far) to fit the floor in place and the cab will snap in place over the steering column, etc. Despite the instructions I did not add the top part of the column or the steering wheel.
Thanks for the comments about the cab/body. I haven't gotten that far. I did do what you recommended with the old Tamiya kit.
