new c10 owner....have some questions

[chappys4life]

Just bought a 82 c10 shortbed over the weekend. 97,000 miles, 305, and th350 tranny. Its a little rough on the outside and the interior is shot. I picked up as a backup driver as my primary driver is a 53 f100 so it can be picky.

I picked up some bosch plugs, msd cap/rotor, and some new door panels. I also ordered a edlebrock 14" air cleaner and accel wires.

I am trying to make this a rock stable driver so I am trying to plan out everything but I have a few questions.

1. What is there for aftermarket exhaust? I cant really find a kit so I have been debating getting a magnaflow high flow cat and a flowmaster dual exit super 40 and running it after the factory y.

2. Does someone sell a whole front end rebuild kit? I am looking for ball joints, tie rods, Tie Rod Adjusting Sleeves, bushings for a arms or do I need to go to napa and order it all?

3. Whats the easiest and cheapest way to get rear discs? Is there a adapter to use gm factory discs?

4. Can I remove the egr system? I have a edlebrock performer intake but it does not have all the egr crap.

5. When I close my doors sometimes the come out like there is a gap between the door and the body but they dont open any more. How do I fix that.

6. Whats the best tonneau cover to get? Should I go the soft with snaps or the hard one that flips up? Never bought one before but was thinking soft would be most practical since it is a work truck still.

Thanks guys for all the help.
