I am not a road racer or even a drag racer, But am going to replace my arm bushing on the rear . The lower i thought i would box them in and put a swaybar on ,all ready have one,whille i had them out . Dang, the thangs are prices, so looking to do it my self , any body got a cheeper place to get the inserts to be welded .looked around and seems to be going for around $40 by the time they ship. Only found two places on ebay. for sale. Any input would be nice.
