Q: What alignment clearances and bolt patterns apply when attaching this replacement travel gearbox onto a 307 chassis?
A: Clean the track frame mounting ring thoroughly to ensure a flat fit, and use a calibrated wrench to tighten all high-tensile base bolts in a cross-star pattern to the factory torque.
