'85 C10 6.0/4l80 project

[PunishedC10]

Got my old job back. So I'm goin to show some love to my '85. It was my dd through high school and college. Figured I'd pay it back.

I have some questions.........
I assume I can use a baffled tank from a '87, 90-91 guage cluster, walbro fuel pump.
What headers will fit? I have read, read, and read somemore and looks like none will fit.
What do I need to do to make the a/c, cruise, and speedometer and ignition to work?
Where can I get a yoke? and will my drive shaft be too long??
Radiator?
I'm sure i'm missing alot of stuff here

On my 86, I swapped a 6.0/4l80e. Used a 91 burb cluster, everything works, need to get my ecm retuned to get the speedo right, just swapped gears...
I went with street and performance headers, pricey, but they fit without a problem and look great.
As far as a/c, depends on how you mount the motor, which plates you use. Mine is set back, and I did not want to notch the frame, so if I wanted a/c I would have to run the hiside kit.
Also, I had a 305/th350, all I had to do was get a crossover ujoint, my driveshaft was correct length.
I am using stock radiator, no problems. I did mount a set of z28 electric fans running off my ecm. Working great.
I am also using an 87 tank with 87 sender and walbro intank pump.
On your stock tranny xmember, you will have to modify, I welded a "tongue" on the backside to accomodate the 4l80e mount which is a little longer.

I dont want to notch my frame for sure. Does that mean I need to follow your path and set mine back as well? i'm just brain storming.

Both you guys have really nice trucks. I hate the wheels that I chose. I think i'm going with bonspeed but haven't made up my mind yet its a hard decision.
I'm sick and tired of the pos 305, its gutless and always something wrong with it. I'm ready to swap this thing
