k10 steering column expert needed!

[chisler]

Hi this is my first time asking for some advice/help so please bear with,I own a1972 chev k10,it is the floor shift model and has the non tilt steering column.I wanted to remove the after market steering wheel and go back to the oem wheel that came with the truck. Here is where the problem comes into play, once the after market wheel was removed with a puller I went to place the oem on,thats when the upper steering shaft slid into the column about one inch, So I had a look under the hood and saw at the intermediate coupling area that everthing had pulled out of the column tube every thing down to the rag joint at the steering box is still attached and looks good.Is the lower bearing/ seal retained by some sort of clip or press fit or bearing preload,the spring is good. Even a diagram would help on how this column goes together.Or even some pics Thanks Frank
