My 1969 swb patina truck, need some help

[murguia]

Just picked this up off of the second owner and I'm finally in a position to build a patina driver.

Background:

Truck came out of Lindsay/Tulare area where it was used as a farm truck all of it's life. I just had a family member contact me about the truck and the second owner wanted to get rid of it so I shot down and picked it up.

It's all original sheet metal with the only rust being in the rockers. It's had one repaint but that's back to the original color. Interior and motor compartment are all original. She fires up but can use a major tune up.

Options (Simple)
V-8 truck with a 3 on the tree

Here is where I need help.

My plan for the truck is to replace all of the moldings, front bumper, grill, tires, powder coat the original steelies and to re-do the entire interior to original.

Motor wise, I'd like to rebuild the original motor in it but I wan to change over the 3 speed to an automatic with a 700 R4 transmission and maybe a different rear end? I want to add power steering and power brakes as well. When all is said and done I'm going to bag the truck so it lays as low as possible without having to cut it up.

I'm wondering how hard it is and exactly what needs to be done to convert to the 700R4 with an automatic and if the rear end on there now will be good or if I should swap it out for another.

Please feel free to chime in on this as I really don't know where I should start.
