KJ,
Thank you for the excellent advice and the link for the receiver.
I will do both of your suggestions.
I'm doing a total rebuild on this vehicle, so the brake lines will be replaced. I replaced the power steering cooler and lines and all other coolers will be replaced as well. I am also planning to rebuild all four corners with wheel bearings, heavy duty rotors, pads and calipers. I retire in 2021 and plan to full time in a TT for a couple years. I have a few years to get the Burb in shape.
This vehicle has kind of a cool history. I bought it this year on EBay. It was listed by a dealer in Philadelphia. The original owner was the FBI and this Burb spent all it's time in the Quantico VA area. I figured it got all it's scheduled maintenance and was well cared for. The undercarriage is spotless.
