9/16" tie rods, Fast Ratio arms, etc...

I recently parted out a 1970 Polara and saved a few of the parts that are not likely to sell online or at swap meets. I saved the 9/16" tie rod sleeves and ends and the Idler arm.
I recall that the 9/16" tie rod was an upgrade for the A-B-E crowd over the smaller 1/2" stuff we had originally. The sleeves from the C body are longer than my stock ones in the Charger. It looks like they are threaded the entire way through from end to end. I am thinking of cutting them to the length of the Charger sleeves. Anyone else here have good luck doing this?
I am not against buying new stuff, I just LOVE finding ways to improve things by using a little creativity.
I already have the Fast Ratio idler and Pitman arms in my '70 Charger....BUT the idler arm from this Polara is LONGER than any stock Idler arm I have in my parts stash. As I am typing this I am kicking my *** because I did NOT check the length on the Pitman arm from that car...I just scrapped it. What if they are a CHEAP substitute for the Fast Ratio arms? The Idler is about 3/4" to 1" longer than an A or B idler arm.
I may put the Charger up on the lift tomorrow to compare the Idler arms. I wonder if I just stumbled onto something cool!
This same thing could apply to your Duster, Dart or Barracuda too!
