welcome, i'll bend the rule on the mandatory pic
the radio being in the center is usually an upgrade, is it a tuffy center console, but yes you can put it in the dash thats where it is originally.
the 4 banger is a work horse motor, i had one. but don't bother getting anything more out of it. if you want more, swap to 4.0 or v 8. and the 4 banger isn't any better on gas than a bigger engine.
you should be able to get all power steering parts fairly easy used i'd hope. you'll need pump w/ hoses, and gear box. not sure if shaft and pitman are different. you'll need a belt to. but that is a worth while investment.
getting a running yj that isn't rotted away for that price is awesome. i paid more for a great body w/ bad motor.
lets see some pics
