Help Needed: '59 GMC 303CSxxxxD

[cjboden]

All, I am new to to forum, have acquired a '59 303CS series truck, set up as a dump truck bed. It has a 270 in line 6, 4 speed manual on the floor, with a 2 speed electric switched rear end. It is manual steering, and here is my first question: I would like to convert to power steering.
Anyone know where to source parts (new or used, conversion or stock) to make this rig go power steering ?
Next: Anyone have experience with disc brake conversions for these bigger (5 ton ?) trucks?

This is surely not my day driver (top speed geared as is, is about 55 MPH) but I like to get it out and use it regularly for hauling. I would like it not to be a practice vehicle for the Iron Man !

Also, any thoughts on what the heck this vehicle is by the serial number designations would be appreciated. I can post pictures at some point also.

Thanks !
Carl
