1970 rear copo spoiler questions.

[ronzz572]

Were the factory installed 70 z28 copo spoilers different in any way from the over the counter spoiler sold? Meaning by part numbers molded under the spoiler and manufacturer of the spoiler 3990475 LH 3990476 RH 480161 CENTER. Most spoilers i have seen were manufactured by general tire, Were they the 1970 only copo manufacturer or is there others?

I had a 70 center that was made by Barnum fiberglass co, or something like that. It had some light damage, and I might have tossed it last year. I put a post on here about it, and it didn't generate much conversation from the 70 specialists......

I have the general tire spoiler on my 70, but I don't think it was factory installed with a O3A build date...........

The COPO 70 and early 71 spoilers were manufactured by A O Smith company. The General Tire manufactured spoilers were later production.

Well spoken Dennis. And the later version spoilers that where made with the new tooling which came on all 71 Z28's as standard after sometime mid year had the same part # with a -2 at the end of the part #. Jeff Cannon

Any one have pics of a A O SMITH rear spoiler showing the underside markings, logos, part numbers?
