The Prothane Total Kit for the MR2 comes with front sway bar bushings that were patterened after the 93 MR2 bushings. They do not fit the 91/92 brackets and only come sized for a 19mm sway bar.
These bushings include new zinc coated brackets and Delrin spacers to ensure that the sway bar maintains the proper distance from coolant lines and body seams.
Sway bars measured with half mm diameters order next smaller size (e.g. 16.5mm bar uses 16mm bushings).
