I've never found a factory jack I liked. I put a cheap 2ton hydraulic floor jack in everything now. doesn't fit the MJ cab very well though. I store mine in a box in the bed.
my 88 still has a carpet dash cover I bought 20 years ago. infinitely better than a cracked dash.
I've seen those rims call "10 hole" wheels. if it had the little fake rivets it'd be an Eliminator rim. If they aren't all corroded, I'd definite;y be happy getting them for a little over 100.
if the carpet works for you, I can see it being worth 75. but I'd need to see it in person.
