The springs I have been using are OME 755 in the back and 764 in the front. The recommended 767 in the front are too hard I think.
I have use QT front radius arms but I think you could easily get away with SuperPro castor bushes.
The rear arms I bent myself with a pipe bender and then welded angle iron down them oto strengthen them.
You could just put a double cardon joint on the original shaft, however I already had one made just needs to be a little longer and I can keep the other one as a spare. I used a D2 tranfer flange and when machined a spigot (light grey bit) to position a more standard spicer DC joint, rather than use a D2 one that you cannot get repair kits for.
Also managed to get a driving light switch of LR for $18 that fits nicely on the dash.
