This kit looks remarkably similar to a Doyusha Countach LP500S. I suspect one is a rebox of the other. My brother has the Doyusha version... we're going to build it some time. It's quite nice.
These seem to be somewhat available too. Check google. Here's one I found on there.

I cannot vouch for this site... it's just the first one I found on google.
