Ya, all the necessary parts are out (and a couple of extras that I wasn't
sure were holding in the heater unit or not ;p) but I also didn't have to
remove my dash and had no problems doing anything from the inside of the
Jeep. My only problems were some of the bolts in the engine compartment.
All-in-all ...not too complicated. Once the rain stops I'm gonna go drill
out a bigger hole and all should be well. Looking back it was a pretty easy
job (except for any rusted bolts and the fact that my rad had to be drained
through the hose because my damn butterfly nut is broken). Still debating
whether to do the heater core tho ...is there a gasket that has to be
replaced if I take it apart?

The stock one stretched fine over mine. I had to use a drop of silicone
on one spot because I was a little off with the new hole.

@#$@#!$ I'm glad you guys seemed to all have an easy time with this ...mine
is being a bitchpig. Nothing as of yet has fit at all smoothly. I now have 5
(yes, 5!) different modified gaskets I've created to try and fit this all
together and still no luck. Like an idiot I threw out the old motor and I
need that little seal off it because the fan gets stuck on the plastic
housing and won't spin. I tried making a rubbery gasket piece in it's place
and it compresses too much when I bolt the assembly back on and it gets
stuck again. So ya, now I'm going back out to modify my 5th gasket and
create a 6th (sorta) silicon seal around the back of the blower motor on the
engine side to try and make a half-assed repair-job of the massive slices
and chunks I tore out with a reciprocating saw. For anyone about to do this
mod ...stick with a jigsaw or build a template and use a holesaw. Recipro
saw is NOT the way to go ;p

*SIGH*!!!

This 2 hour job is now a 2day job. It's a Jeep thing.

On the plus side tho, that motor sure does blow air alot better and I tested
mine outside the assembly and it was actually starting to fail a bit (slow
down, speed up, slow down, etc) so it'll be worth it when it hits -30.

I didn't use any gasket on the back of mine, I remember looking at the one
on the old one and thinking I should try and get that off and reuse it, but
I forgot, and everything turns fine, the most it might do is suck a little
air from engine bay, may run a bead around it, coarse my hole is withine a
1/16".
