[burnin oil]

Do yourself a huge favor and replace all the brake lines. Also pull the inspection cover off the rear end, clean, and refill. I just opened up a HO72 axle that the oil looked more like grease! It wouldn't be a bad idea to pull the rear hubs and clean the bearings and install new axle seals. You dont want oil leaking into the brakes. Other than those points it's a good looking old truck. Good luck with her.
