Car'* got the FE1 suspension (30mm/14mm). I was thinking you were talking about the automatic leveling stuff with the compressor up in the engine bay. Pair of air shocks in the back probably wouldn't be a bad idea. I added about 40lbs to the rear end with the hitch and the Nitrous bottle is another 35lbs on top of that. Who made your air struts?
Mine are Monroes... My 91 and 95 actually use the exact same struts all the way around...

I actually bought Monroe Matic Plus struts... Been about 3 years now with no issue and the struts still have a nice ride... They would be worth it on the rear of the 91 LE if you plan on any towing...

I replaced my 14 mm bar with an 18 mm bar... The driffrence was a nice improvement on the back end.. Even better if you can find a 32 mm for the front to give it the proper balance... But changing from the 14mm to the 18mm on the rear seemed to help out... You can actually use any Bonneville 92-99 18 mm rear sway... Most should have the 18mm if its the SE model

Looks like it fits fantastic. I too think the LN3 would have no problems towing, but I don't trust the brakes stopping the car by itself let alone a couple thousand pound load.

Trust me. I've had my hitch on BOTH Bonnevilles at different times. It'* currently on the SLE (it moved me to my new place last month). Go with a BIG trans cooler, consider a trans temp gauge, and make sure your brakes are all in good shape. Regardless of trailer weight or size.
