South side machine ( if you can find any, they are considered the best and original but the company had gone out of business)
I opted for jegster traction bars, they are the same exact thing as the SSM pieces But with sphirical bushes instead of solid. Of course they are not a direct fit. You will need to check and set pinion angle, and drill holes for brackets. All said and done, well worth the labor and $$$. You WILL see GREAT results! Are you thinking of drag racing? These are not for corner carvers.....
