For the tie rods, upgrade to larger diameter (11/16"?)is available from the parts store. I believe you are looking for later 70's C parts (eg Dodge Monaco). Firm Feel, Mancini and others also offer these.
I did this with the hot rod. The adjusting sleeves were a bit long so I trimmed both ends of each sleeve a wee bit to get things in spec.
