The 25/19 sway bars were purchased from JUSTBMWS.COM (800)466-8184, the bars are adjustable and cost $269.00 plus shipping. Caution, with my automatic transmission, the bar was touching the bell housing (even though both tranny & engine mounts are in good shape). I changed the brackets to 88 M5 which are designed to hold 25mm (they are wider & heavy duty with two bolt holes). I had to fabricate two steel plates with two holes matching the M5 brackets and weld one stud to the bracket and use the existing threated hole on the frame, to bolt to and weld the plate to the sub frame.
