Bump back to late 80s and get a Revcon. No leaks or delamination. Handles/drives better than any DP. If you love working on classic cars, you could very easily fall in love with a Revcon. While technically the tow rating is 2000 lbs, I tow my 4600 LBS Grand Cherokee everywhere - including Colorado mountains. Traveling through MN, and SD, I set the cruise @ 82 mph and yes that was towing the WJ. If you tow that much weight, it would be wise to ad a rear trac bar. The Jeep gave it a little understeer. It was fine towing the 3100lbs XJ, but when I switched to the WJ, the trac bar was required.
The interiors as they progressed through the 80s became nicer and nicer. All Formica laminate over solid would frames. Hollow core doors. Everything is very solid inside, and the Formica holds up like new, even though its pushing 30 years old.
I will tell you, it can really be a pleasure working on old high quality stuff. The drive train is a custom front wheel drive, however most wear parts can be easily sourced from any parts store, once you know what you are looking for. Being that you own a Cobra, you will be interested in knowing the drivetrain and suspension was designed by Peter Bryant who worked on the Cobra GT40, and GT350 programs with Carroll Shelby. Could be an interesting match of toys.
