Getting ready to replace all of the suspension bushings on my 77 450 SL. Should I buy new upper control arms since they come with new upper ball joints or can I just replace the bushings in the upper arms that are on there now? Any need to replace the upper ball joints or do they not need replacing? Car only has 100,000 miles on it and has had no abuse what so ever!
Thanks,
Mike
PS....What about replacing the "flex disks" too?
