Thanks, Sully.

Yes it had 4- bolt Jongbloed wheels then. MANTA2 was originally built with a VW trailing arm front suspension but they had started to covert it to a Mustang II when the company went out of business. When I bought the car (in pieces) I finished the conversion. It now has 5-bolt hubs.

If you look at the "Manta Detail At Sears Point" group of photos you can see that the Mirage started off with much smoother fiberglass than the ones produced later. The fiberglass was thicker as well.
