I replaced the factory front swaybar with a 1" from NPD. Factory was either 5/8" or 11/16". The kit came with 1" mounts, which I did not know. I purchased this 1" bushing kit.
The factory swaybar causes the end links to be tilted back, when used with the coilover suspension (see pic).
I heard you would have problems using a 1" swaybar with an FE. I seem to have no clearance issues. Only problem with this bar is that it does hit the frame when the tires are lifted off the ground. So this should only be a problem when I pull my General Lee "jump the river" trick.
I used the old end link bolts and had to shorten the bolt spacer in the (middle) about 3/8".
