smoky02,
Like I said in my PM, I didn't have all these choices back in 1989. If you have the wiring harness you can use it if it's not cut up. Make sure you mark everything that is unpluged for reinstallation. Less headaches when putting it back together. This was the reason for the S&P wiring harness.
If you are going with the 700-R4 transmission you will need to cut the drive shaft off some too. I don't remeber the amount but I'm sure someone knows.
My motor was built stock and I'm getting 18-20 MPG out of it. No it want win no race contest but for everyday driving you can't beat it. It cranks right up and ready to go on cold mornings here in SC.
The high pressure rubber fuel lines are fine to use. Just make sure you use a good connector with them.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
