67 Valiant spool mount

Hi,
I have a 67 valiant that I am putting a spool mount k-Member in. I have been doing research on what parts I need to get and have been seeing different answers. From what ive found I can use the lower control arms off my s6 k member and I will need so source 73 + upper control arms with big ball joint. Would that be correct? Ive read that I will be able to use my stock idler arm and center link but ive also seen that I will need a 74-76 center link. If anyone could point me in the right direction that would be awesome.
Thanks
