Burbank's House of Hobbies.
Smith Brothers Hobbies in Northridge.
Pegasus Hobbies in Montclair (a bit of a hike but worth the trip).
Check out the Nethercutt Museum on Sylmar.
One of the Japanese companies made a /16-scale kit of this car many years ago.
Also Tron Models made a 1/43 resin kit. There's one on eBay right now.
PS this car was larger than a Dino so a conversion from the Dino kit is not realistic.
