I have an old draw-tite in my barn. The issue with it is that it needs something on the front of the car to connect too. I made a flat bar that could connect to bumper brackets that extend from the car. If yours doesn't have the bumper brackets sticking out there isn't anything to connect it to. Just hooking it directly to bumper brackets would wallow out the fiberglass either side of the brackets (plus the bumper brackets aren't very strong - being held on only by four 1/2" exhaust U clamps.
I narrowed my VW tow bar (about 2" to clear the front bumper brackets) but did NOT lengthen it. I towed with both a Yota 4WD 4Runner and a 4cyl auto Camry with no issues. I used a $20 HF adjustable height receiver on the 4 Runner to get the tow bar level with ground. On the Camry it was just a slightly lifted receiver that stuck out maybe 6-8" from rear bumper. I was cautious on not making 90 degree sharp turn, not backing up and traversing drainage gulleys/speed bumps at an angle.
I towed My Speedie 1k miles VA-FL with Camry (17 hrs). From condo to my barn (1.5 hrs) with 4 Runner. Towed Dale's TD replica to Carlisle and back (in rain) couple times and rescued Ed's TD one year at Manassas bugout.
You are welcome to borrow any of mine. I have the slightly narrowed one, a stock VW one, and the draw-tite one. The VW ones are big and bulky to ship (maybe GreyHound?) and the Drawtite with extra plate is just heavy. One of my VW ones takes a 1 7/8".
My Speedie is lowered with 2 Avis adjusters (not dropped spindles) and has 185/65 tires. Do you have 2 taller tires (80 series) vs whats on it now. That could raise it 1".
This is generic draw-tite --- not the older one I have. Mine is very heavy but can be folded for transport/storage.
