Thanks Bill. I ended up with the kit from VCI (Vehicle Craft) today. Complete kit: $195 + shipping.

Thanks again for all your help.
Week 7 pics of the project ought to be up next Sunday. The big job will be cutting/grinding the rear control arms to accept the rear turbo calipers.
Looking forward to that.
