The 1354 only came behind the 4.0. Any 89-97 ranger with the 4.0 will have the 1354 and a few 91-94 Explorers. 95-96 is the only years that don't require changing the driveshaft, 97+ you need a 95-96 explorer front drive shaft. A 1350 linkage may or may not be able to be used, if depends on which one it is. I had a 1350 linkage that I modified to work but later swapped it for a 1354 linkage. When you get the linkage, make sure you get the bolts that go with it. The pivot bolt is a special bolt and would probably cost a few bucks from ford. As far as 1354s being hard to find, I didn't have any trouble finding one. Look on
