Finalized the steering today.
I drilled out the center link with a 12.5mm cobalt drill bit. That opened up the tapered hole to .492". A 1/2" shoulder bolt measures .496". So I honed the hole with a drum sander to .495 and tapped teh shoulder bolts in. That produced a really nice tight fit.
I painted the center link with my usual hammertone gold. It matches gold irridate and is the toughest spray paint I have seen out of a can.
Here is the stack up of washer on the new inner tierod. I can now adjust my ackerman. I still need to develope a good way to measure it. SO I matched stock.
I used the regular chromoly rod ends on the inner pivot, 5/8-18 thread and 1/2" hole in the ball.
Here is a picture of the outer tie rod spacers. I added washers to adjust bumpsteer if needed in the future.
The larger OD stainless washers are being used as a safety washer incase I ever have a rod end failure.
The outer tie rod uses a high misalignment chromoly rod end with 60 degrees of articulation. It has 5/8-18 thread with a 1/2 hole in the ball.
And finally a installed view at full droop:
Time for a test drive!
