I got mine for $300....and yes I'm bragging! :lol: The guy was parting an '85 442 and knew it was an 8.5" but didn't think it was posi because he couldn't find the rpo code. He could have also looked at the big honkin posi tag on the cover too! I just nonchalantly spun a tire, observed and kept my mouth shut. It pays (literally) to know what you have. It's nice to catch a break once in awhile.
