I'd go with the roadmaster baseplate just to keep it the same as the two bar. I towed a 91 escort and it was a good tow car so I bought a new focus to replace it.
Escort/focus make a really good tow vehicle as long as you don't need 4WD. I think it is a good tow, has enough room in the cab and plenty of room for groceries or other camping goods. It's lightweight and it tows nicely.
The Falcon all terrain is the same as I use and is a good tow bar.
The xl baseplate is 330 bucks here:
The seem to be the cheapest but don't try to call them - they never seem to answer the phone. If you order online you will be ok. You order through them and roadmaster will ship out the base plate from their warehouse.
I got my baseplate for the focus a few weeks ago but have been waiting for good weather to install it. It's too cold here in the northeast to crawl around on the ground under a car yet.
Your model looks alot easier than the focus and just a little more difficult than the old 91 escort that I had.
