I'm glad you mentioned the issue regarding collapsing. I was thinking of painting or clearing mine as well, and soon.
I don't know if I messed up on my install, but I can see you have almost twice as much "give" before bottoming out on the bigger shaft.
Or, to put it another way, your steering column would be just touching your chest, compared to mine, which would be an inch INTO my chest!
It's been so long since I did this I can't remember the measurements. I do vaguely remember thinking I messed something up... Then again I put in a different steering box, so it might be that.
Good for me I have long legs and arms, so I'll just put my seat back just a little further.
Your engine bay is impressively clean, looks great.
