Is it a fit problem? From my understanding, the ones from the Granada should fit. A little more info may get a better response. Is your 65 a 4 lug, or 5 lug set up? I don't know if that makes a difference or not. Try doing a search, and looking at the article in the FAQ section.
You will want to use the Mustang inner tie rods and Granada out tie rods.
Note, if you have power steering, your driver's side outer tie rod will require a special (ie expensive) tie rod, available from Mustangs Plus. The passenger's side with power steering is fine though.
Clarification- If you swap to the Granada tie rods, everything bolts up. if you keep the original tie rods, the shims fit into the spindle hole to take up the slack and it fits tightly without having to change tie rods.
