Some cracking progress there
Are the wishbones roughly based on the Saturn design? If so you may have a problem with the steering arm extension hitting the lower wishbone. You can get round it by limiting the amount of steering lock as it only just hits on full lock.
I know Phil made some lower wishbones with a slight bend in them to get over this as well I believe for the Voodou design I think.
Any thoughts on how you are going to mount your diff yet? It's been a topic of much debate in the past on which way to mount it.
Looking forward to more photos...
