Suspension on 63 cdv

[Kim K Kaiser]

Hi all.   my 63 has developed squeaks and creaks recently.   I took a look at the ball joints and associated rubber parts, and they do look a bit worn.  I have replaced shocks in last year or so.  When I bounce the front ends, you can hear the squeak and "feel" the squeak when you put your hand on the upper control arm.  I put some oil on them to try and settle it down for temporary relief. I feel like Uncle Buck riding around with the squeek at stop lights!!   the prior owners that had the car  since orig purchase kept meticulous records and I cant find any efforts to replace them.  That would mean they have 175k miles on them.   

So I was wondering if it would be wise to replace the control arms with the newer configurations or just replace the ball joints and associated rubbers.    Would the newer engineered arms be worth it ride wise?  and if so, is any cutting or refitting required.  and further, is there any kit that anyone could recommend??
