Interchange of clutch and slave cylinder from 90 to 87

I have a 90 model ranger with 2.9 and had to replace tranny.I got a used one from a junkyard and found that it was a little older but a more heavy duty tranny .It is a TK 5 I then had to aquire a shifter. Now that I'm ready to put it in I noticed the 32pilot bearing isn't the same design in that it doesn't bolt to the tranny like the other one.That has caused me the dilemma of which bell housing to use.If use the original one I can't use the original slave and throw out cause I don't have anything to bolt it to and if I stick with the parts on the one i bought I need to know will my truck interchange tree . with the older clutch and slave cylinder ?
