Wow are you lucky - what a great job you are doing ! Wish I could have done something like this and learned how to do all that stuff. I know how to do mechanical and electrical work, but welding is just something I never learned.
I noted in some of your earlier posts that it looks like you have the old style tapered axles, I hope you are planning on getting the later style axles for your car. Somebody once told me those tapered axles tend to rip out the woodruff keys used in them when alot of power is applied to them.
Good luck with the build and keep posting !
