...a 4 speed manual transmission (not sure if its bw or np).
Aluminum top cover = NP435; cast iron = BW T18/19. Read this caption & fill in your profile, AND create a detailed signature. Location would be good, too.
in order to only buy one set of drive shafts ...
You don't have to buy any driveshafts. Just have the current ones cut for length after everything is put back together. But depending on how much you lift it, they might work as-is. You can't properly set up the driveshafts until you have the truck's full weight on the suspension.
what parts will I be able to use from the pedal assymbly all the way to the clutch/flywheel/pressure plate and starter?
If you're asking about using the '84 pedals in a '95 body: NO. Everything else depends on what engine & transmission each one has now, which is why it's important to put that info in your profile & signature. Post the details of the '84.
The clutch/fw/pp were brand new 10 yrs ago less than a mile on them.
"Brand new 10 years ago" = "OLD".
If they have no wear, then you MIGHT be able to reuse them, but time doesn't stop just because a vehicle isn't driving. Sitting is harder on a vehicle than running hard.
With the combination of the 351w and np435 what trucks should i look for a bell housing out of?
All engines in the smallblock family (which includes a V6, the I6, a few V8s, and even an early version of the 4.6L modular) share a bellhousing pattern. Several manuals share a front bolt pattern. So the bellhousing can come from a LOT of pre-'90 trucks & vans.
What are some major concerns with the pcm other electronics and fitment?
Concerns are as major as you make them. If you know your wiring, it's no big deal. If you don't...
But without more specifics FROM you, I can't give many TO you.
Who do y'all recomend for drive shafts local shops in Mississippi or online?
Mobile, or Tupelo? We don't know what "local" is to you.
I also want it to come in at less than $8000 including new 38.5s and wheels is that reasonable?
Do you know where all your local junkyards are? Are you willing to spend a LOT of time in them?
