The ones I'm thinking you mean, used to be listed on FFR's parts catologue, but I couldn't find them, so I couldn't confirm exactly the pieces you are looking for.
Do you mean those two stainless extension pieces, that thread on to the inner steering rack, and then the inner tie-rods, in turn, screw into them? Used on Ford 87-93 power rack, I think to help with alignment perhaps??
If so, I think I still have a set kicking around..need to do some digging before I can confirm. PM me and we can discuss price.
