I have not had the car suspension setup by a professional. I am sure that it would help out allot. I have no idea who to take it to.
Here is the list of rod ends and aircraft grade AN hardware I bought from Pegasus to do the front and rear bar:
3061-6-R - Rod End, 3/8 Bore x 3/8-24 Right Hand Female Thread   QTY. 4   
AN365- 6 - 3/8-24 Nylock Hex Nut, AN365   QTY.   6   
AN6-11A  - 3/8-24 x .562 Grip Airframe Bolt   QTY.  2   
AN6-15A  -  3/8-24 x 1.062 Grip Airframe Bolt QTY.4   
AN960-616  - 3/8 Flat Washer, .063 Thick - 100 Pcs   $5.79 QTY. 1      
 Thanks,
