Alot of circle dirt tracks all across the country runna street stock class that uses metric car frames & some allow aftermart, upper A-arm so they run the ? on right frt & ? + on the
on the left. This of course, to help them handle in the corner. Speedway Motors have these everyday for about 50.00 ea, plus B-joint. I'm not sayn that the ones mentioned in the above post are that, but I am sayna they will work. They come in many variation, adjustable or not, mopar b-j or Gm b-j. If you've been to cirle track, the upper arm are plenty tough. Yes I have them, with B-body spindles & brakes. They also have a rear brake kit to put disc on the rear,( waitn on warmer weather & time) the research is on this board. You can also see them run on IMCA, Usmts Modifeds, Sport Mods & others.
