Plate
Note:
Plate thickness should be ~8mm (5/16”) ~3/8” , it can be thicker, but should not be thinner (to accommodate counterbore)
Material is whatever is available the easiest, aluminum or steel does not matter
The distance between each pair of holes is the critical dimension, from longest to shortest length of hole pairs: 17.4”, 16.7” and 11.1” corresponds to the tie rod, push rod and UCA respectively.
Surface machine the plate if there’s time to make the jig better toleranced.

Assembly/Usage of Jig
The plate is designed to be used with the tie rod, push rod and UCA by moving the spacer and bolt to different hole pairings.
Assemble the plate, spacer and bolt nut like the figure below.
The plate and rod end is sandwiched between the spacer nut and bolt with the bolt entering from the counterbore side of the plate.
