It's ALIVE!

[hi guys] First post to this board, I've been lurking around for about three weeks trying to get some info and whatnot, and finally decided to register.

I need help.

I'm still taking the truck apart, trying to figure out what work it NEEDS. here's a VIN cs149j845065.
nothing has really been done to it aside from some very poor body repairs and the seats were replaced.

Anyway. my first question, I'm trying to figure out what two of the original options from back of the glove box door sticker are (they've had some stuff spilled on them). where can I look this up? or does anyone know what 4Z52AA and 4525AA are, one of them (I think) is the original seat.

Next question, the bed (fleetside standard) is... crap. when I bought the truck it had some plywood over the wood bed floor which was covered in dirt, then a layer of pine needles with some gravel and snow added in for flavor, when I finally got all that stuff cleaned out, I was sweeping the bed out and found myself standing with one foot on the garage floor! WTF? the wood was rotted through and the cross-members are rusted through (frame's okay though). I guess my question is: once I take the bed parts off, what are my options? can I get a stepside bed from the junkyard and have it fit? do I have to stick with the fleetside? what about something with a steel bed floor?

I found a junkyard with a stepside w/ some dents not too far from here (I'm in St Paul,MN)and at a fair price, I'm okay with dents 'cause that's just hammer and dolly work... so, will it work?

any help would be greatly appreciated.
