I don't know about any commercial ones, but I converted my A-arms
to adjustable heim jointed arms several years ago. We did a similar
conversion to Chip Bond's car at the SCCA Runoffs last year.
Basically, you need to cut off the end of the arm where it attaches
to the frame braket and weld in a piece of internally threaded rod.
This fills the space in the U-shape of the channel that's left after
cutting off the end. Then you just thread in the large heim joint
until the camber is correct. You'll need to make up some spacers
since the heim joint (or rod end, as the 'mercan race shops will
know them as) is a bit narrower than the rubber bushing that it
replaces. Of course, you'll want to be sure that the weld is done
correctly...
