Why are you using standoffs to attach teh palte to the 2x1?
Why dog shifter over ball shifter?
We're using standoffs/spacers to attach to the 2x1 frame because
- the steering gear goes between the spacers on top of the 2x1 below the bottom gearbox plate. You can see it on the third render, bottom right corner.
- It gives us 2.25'' ground clearance instead of 3.25''
-It allows us to put nuts between the bottom gearbox plate and the 2x1, which lets us remove the top gearbox plate independently for gearbox repair

We're using dog shifter simply because we have some parts already in stock, and because we haven't discovered a definite answer on CD about whether ball or dog shifters are better. Aaron has tried another version using ball shifter, but only saved 0.5'' in height, which we agreed was not worth buying new parts.
