1967 5x4.75 help

[chipmaker 1985]

Hi Guys, Long time lurker 1st time poster.
Needing help converting my Dad's 67 to 5x4.75 disc.
He has a set of wheels that he has his heart set on and I want to find a way to make it happen for him. From what I've read we can get a stock spindle bolt on kit, but it will increase the track width. I'm still not sure if it's 1.25 per side or over all. I don't believe we have the room for 1.25 per side.
Other option is, we have a set of spindles and calipers that I believe to be 71-72 but I'm not sure how to confirm. I know they make a 6x5.5 to 5x4.75 conversion rotor for the 71+ but I'm unsure of what ball joints and tie rods/ adjuster sleeves to use.

I'm thinking it would just be the conversion rotors, 71-72 ball joints and tie rods with the conversion adjuster sleeves if I can confirm that those are indeed 71-72 spindles

Any advice y'all can give will be greatly appreciated. Dad's getting on up in his age and has already had a heart transplant, I want to do everything I can to get him in his 67 ASAP

Thanks in advance for any help y'all can offer
