K member setup

Hello FABO!
Working on a 67 barracuda fastback BB (383) 4 speed.
The last time i slid my passenger T bar in, i was reminded of a patch weld i put in when i didn't know any better. As a result the LCA is slightly canted up and the T bar needs too much coaxing to go in. So for now I'm just leaving it to be able to finish the build on the car, but in the back of my mind, i know this will have to be addressed. I picked up this later K member hoping to kill some birds.
1. Getting rid of 'one year only ' 67 idler.
2. Hopefully gain better pitman arm to header clearance and get rid of driver side motor mount spacer.
3. Have proper T bar installation.

When attempting to achieve these goals I'm looking for intel on....
1. Does this K member require a different center link to run with a different pitman arm? Does this change require a different steering box?

I have parts like LCAs, UCAs and spindles, so my plan would be to build this, looking DEEECENT, and do a K member swap. I have adjustable struts and would consider adjustable UCAs. I have some Kelsey Hayes and converted BBP discs to throw on as well.

So, center link, pitman arm (and will it solve my header clearance problem?) Obviously idler will change.

Thanks FABO! You guys n gals rule!
