New to K5! Just picked her up! Need advice please

[Cyfans4]

So I just picked up a 72 family fun ride - and love it! 454, red, 4x4.

I have a couple of questions:

It came with a double-wall hard top, but I think I want a soft top.! Any idea what the hard top is worth? It got some cracks, but the glass is good, a few cracks on top, but not leaking.

I need to seat 6, and plan to go to a junkyard to find a truck with front buckets with bucket seats. Anyone know what I should look for?

The power steering seems 'loose' - what should I look for myself before I take it to a mechanic?

Somebody at sometime put a huge fuel cell in it, am I SOL in a receiver hitch?

Thanks for any advice!
