well, ive had enough of my new cokers being "frame sanded" in the rear . i dont really have the materials or the right tools to make a panhard bar, so is speedway problobly the cheapest way to go. i have a four bar so i thought id be ok, but im not . i need a panhard
if you have a triangulated 4 bar, you're likely to run into some problems of the panhard bar working aganst the 4 bar setup. if it's limited in travel, it may work okay. but what moparsled said, hit the boneyard. or else the cheapest way to do it with all new stuff is to get some bushings and matching tube from suicidedoors.com, a lenght of 3/4-1" tube and weld one up yourself and fab the brackets from plate.
not all the coil spring stuff.....the a & g body stuff is triagulated.....the big body stuff from the late 50's and 60's have one......look into the late 90's buicks and such .....and some of the front wheel drive stuff.....brandon
