That thing is awesome.
Looks like a pretty clean job too, and not to over done like these custom cars tend to be, the front wing's doesnt quite do it for me, but I absolutly love the rest of it. Nice touch with the shifter.
I've always had a love for these old Datsuns, one of the few non-USDM cars I even like, and yours is certainly one of the better ones I've seen. I'm looking forward to reading about the build.
