I was looking at your set up in your pictures and was wondering if you dremeled your top center diff mount or just twisted your carb a whole bunch , or a little of both for your carb boot not to rub the center diff mount? I had to dremmel mine a little bit. My friend is building one with the same engine as yours and the carb boot is going to hit. We both are using the losi engine mounts that come with a kit. Im not to familiar with the quick change engine mounts, but do they enable you to move your engine towards the rear of the truck so your flywheel is in the exact center of the chassis opening, and also enabling the carb boot not to rub the diff mount? I just dont really like how the th/brk linkage sets up on these things with the boot rubbing.
