I dunno much about the SC10... are the towers interchangeable? I know the rear 'bumper' attaches to the top of the SC tower... but other than that, would one just slap on the T4?

Im curious as to the actual OE 4th hole position... and if its why i feel i may need another rear downtravel limiter.

Using another tower as a jig seemed like it would keep the geometry the same (downtravel staying the same through the range of upper positions)...
