that car had some very interesting suspension "tricks" done in the rear.not so noticeable unless you were really looking,or had something side to side to campare it to.i actually copied that setup once when I worked at a local chassis shop.lots of fab work,as you just cant buy some of that stuff.there is some some ss cars in the area still using those same mods,goes to show you,if its not broke,dont fix it......that setup worked like magic.....I believe the chassis guru john holt was behind that design.....john can make an icicle wheelstand on the Alaskan tundra.....
