I just checked my parts book, (model 172 and 175, 1962 and earlier) page 32 and 33 show the horizontal stab, and it only shows 2 part no.'s for complete stabilizors. part no 0532001-200 fits 172's 1956-1960 and 175's 1959-1960, part no. 0532001-201 fits 172's and 175's 1960-1962. the only different parts on these 2 stabs is the tip in front of the elevator counterweight. an online parts manual for 1963-1975 models shows a stab part no 0532001-2002 that fits 1963-1973 172's, this appears the be nearly identical to the earlier stab except it is extended about 2 inches on each tip for a different elevator hinge and counterweight. looking at the drawings it will probabally fit the tailcone, but will also require the 1963 or newer evelator to go with it. good luck getting the FAA to approve it.
