65 to 72 Disc Brake Conversion

[6T5C10]

I need some advice and/or knowledge. I have a 65 C-10 that I will be converting to power disc brakes. A friend gave me some 72 spindles with the calipers. I am replacing all of my front end pieces with 72 parts. I can't find a 72 centerlink. How can I connect the tie rods (72) to my 65 centerlink? Can I use a 65 inner rod with a 72 outer? If so, how do I connect them? I know I am not the only one that has run into this.
