Got your comment on my site:
To adjust - support the chassis with a jack unloading the suspension.
Remove the nut either end of the top wishbone on the chassis side and pull out the rod that goes all the way through.
This is an old photo with the stock for ford TCA bush (Marlin since stop selling these and only supplied the powerflex ones in the above photo) as well as showing the wishbone installed up the wrong way.
However it does how the threaded part used to adjust camber. Undo the nuts and twist them in or out on the thread to make the wishbone longer, or shorter, as needed. Make sure they stay the same length relative to each other.
It's a pretty slow process setting this up as you need to assemble the whole thing, put it on it's wheels bounce / move it and re-measure.
