Russell, I used a OEM shifter out of a Dodge Van in my 63 C20. I had to space the shifter off the bracket by about 2 inches so the rods would clear the transmission. With the spacer the shifter is just inside the left side of the hump. I haven't driven it that much but there doesn't seem to be any problems. It's pretty close to jfnar's second link.
olememphis, There is a trick to rebuilding the 833. There was a post not long ago here that said there is an assembly that is spring loaded and should be kept together. Sorry don't remember the subject.
