Tubular control arms vs rebushing

Avoid Moog ball joints. They are junk. I've been using XRF ball joints and they perform great and so far are much more durable.
Here's a link to the manufacturer. They are available online in the US, but call or do a search to find out where.

Inspect the upper attachment points of your front shock towers to the inner fender. Mine were all but broken loose.

Buy the rebuildable idler arm. If you have power steering, get a Firmfeel box. I would have the shoulder for the washer stop on the strut rod's machined back about the thickness of a dime and verify that the new bushings do not increase their overall installed length.

Also, C-body tie rod ends can be adapted to fit in A-bodies and are much stouter.
