Check the A body "parts for sale" (on here) and or place an ad there. I believe /6 and V8 ones are the same 68-76 ex 73-76 the tie rod mounting ends w the tapered holes are turned 90 deg and the pitman/idler tapered holes are larger at the top (castellated nuts on the bottom as the tapered shaft(s) enter from the top) and it will interchange but requires the matching pitman/idler arms that enter either thru the top (73-76 or the bottom (68-72) and I may have that backwards on which year group enters from the top or the bottom. The 73 up one sits a bit lower for added pan clearance. When I put a 400 BB into a /6 69 valiant the shallow /6 center link cleared perfectly. Also pitman arm there might be a change on the other (splined) end for PS in 73 up but not sure exactly the diff on them but be aware if that if need be
