Part pricing help

[that_red_c10]

I've decided that I want to start to get my truck pulled apart and I want to put on the correct parts that it had in 68', rather than the 71/72 gmc front clip I have on plus some other parts, so I just want to get an estimate as to how much they will cost in decent shape (OEM only).

I need:
68' Front Clip, pretty much the whole clip minus the hood. I will need all chrome as well.

Not absolutely necessary but I might need 8ft fleetside bedsides, I will need a tailgate.

I will probably need doors as well.

And just in case I decide to just swap my parts onto a less rusty truck, roughly how much would a stripped rust free cab with title cost?

Again I'm looking for just an estimation as to how much I'm looking to spend for each lol. If anyone's purchased the things I'm looking for, how much did you pay for them if you don't mind me asking?
