hack n tap install
 

I bought a hack n tap kit from iro. will I need anything to install it other that what comes in the kit? it'd going in my 89 cherokee with np231 if it makes a difference

I highly recommend getting some cutting oil. Use it when drilling, and especially when tapping. Go in a quarter turn, back out, reapply cutting oil. You don't want to break the tap off in your hole so go slow and use lots of oil.

Make sure you cut off enough spline. I did mine tuesday (H&T from IRO) and I didnt cut off enough spline, so my new yoke doesn't engage my seal very well and it leaks a little

As long as you have the pre-96 flange and the right tools you should be good
