Seems pretty complete to me.

For $12 on this amount of work, why not go for "better" - if it is 
indeed better and not just higher priced?

>> C) There seems to be two different pilot bearings available, again

Maybe they are not even the same part.

Yes... add that in.  I didn't do mine years ago and smelled transmission 
goo to regret it.

>> E)  Any intel on the least painful place to get part #2?
>> F)  I assume the downpipe has to come off (sweet).  Is that gasket

Maybe, but again, new is $cheap.  The manifold to downpipe gasket (three 
"holes", five bolts) should be replaced, as should the locknuts.  The 
downpipe to cat "donut" can probably be re-used, and is also easy to 
deal with if not, later.

A good point, but if he is not "poor", the mounts are cheap, and the 
hose is best replaced now.

A plastic, cheap part, that requires many hard hours of labor to get to 
is best replaced "while you're in there".

Sorry, but they don't all "leak a little bit".  just as we replace the 
front crank seal when doing a water pump/timing belt, the clutch job is 
the time to throw in a new rear main (and tranny input) seal.

Not if you do it right.  If you can't do it right, you shouldn't be in 
there on your own anyway.

Agreed, that preference, available cash, and long term plans for the car 
all come into play here.  Sorry if some of my preferences seem to 
disagree with yours so strongly...

Agreed.  There are these silly little gasket like things, that seem to 
be re-usable.  Then again, a big parts order with planning might as well 
include them.  if one is aware they exist, in advance.

See above.  N/A cars have downpipes, too.  They usually lead from the 
manifold to the next component under the car.

You would probably do well to at least inquire at Atlantic Imported 
(down the road from me):


The web site is kinda psychedelic, to my eye and taste, anyway, but just 
call and tell Klaus or Wolfgang what you need.  They'll understand. 
Klaus made Saturday AM deliveries of TB/WP "kits" long ago when we 
embarked on this fiasco:
