I just did what you are about to do to your car earlier this year. I had a local shop tackle most of the suspension stuff though but here are some suggestions. Mind you I have an Ebody but pretty much using similar parts

Front end Hotchkis:
Get some grade 8 or higher button head bolts for the tie rods because you might need them in case you need clearance at the wheel due to the tie rod bumpsteer spacers. I ended up not using the hotchkis aluminum spacers and was able to get shorter steel spacers at the hardware store. I am using a 10.5" wheel so you might not need this for a narrower combo. I would also get the rubber booties for the rod ends as well.


brakes:
I used an aluminum MC from a dodge truck but I have hydroboost though. The pedal feel is great but I can't heel toe anymore as it grabs way too quick. I just changed my driving style. I still have to swap to Carbotechs

Cass sent me another distribution block to use, I would email him again.

8 3/4:
only thing I did different was get 1350 u joints on both ends.

wheels:
I would get 2 rain wheels and tires with deepest offset and using a variety of aluminum spacers to find the exact offset you need front and rear. You might be surprised that a wider tire might fit! I rolled my fenders too.


Hope that helps!
