Do the front mounting brackets come through the floor on yours too? Do you have a diagonal link or a panhard bar?
At first I ust had a single diagonal bar running from lower left front to lower right rear, but I figured a piece of pipe can withstand a fair amount of tension when pulling on it (turning right), but when you compress a pipe (turning left), it's easily able to bend out to one side and your a goner then. You wouldn't want that happening at speed. I then decided to strengthen the bar (larger diameter) and also make a diagonal bar in the other direction. I'm not done with it all yet, but it's getting there.
