Subframe connectors for a vert!

[93yello1]

Looking for suggestions-I have a '93 LX 5.0 ragtop and I would like to add subframe connectors to help rid the car of the twisting and flexing. The car isn't raced or really driven hard, but would like to correct what Ford didn't in all these years.

What are the advantages/disadvantages of full or standard length connectors? How is the ride quality affected? I realize weld-ins are the way to go, and another question I have is that the car has the "reinforcement" plates riveted on in front of the rear wheels, which I was told by a local Ford dealership that has modified Stangs that these shouldn't be removed no matter what, that it will create more problems, what's the truth, what does a person need to do, what to watch out for and what make of subs are recommended other than the MM, since they seem to require alot of welding, and in my situation, a simpler type should be fine?

Thanks for the help with this!!
