GM Stocker rear end

[Dave1695]

The 9 inch rear end in the COPO cars, is built by Strange exclusively for GM and the COPO program. Not available to the public, unless you buy a COPO of course.

"Original rear end may be replaced with another from the same
automobile manufacturer"

That wording is not in the rulebook. In my mind it makes no difference who made the housing...it is still from the same car manufacturer. Did the COPO cars not have to meet the minimum requirements to qualify for Stock classes? My Mosier or Strange 12-bolt housing was not built by Chevrolet, but are none the less considered legal...correct?

OK, now, is the COPO rear end in the Camaro built by Ford or an aftermarket supplier? Seems to me most rear ends are made by Eaton,Spicer,Dana or some outside party like that. Does that mean I could put a rear end that is a facsimile copy of a 9 inch Ford,although not made by Ford specifically, in my 327 powered '68 Chevelle?With the currently increasingly more difficult to locate and expensive OEM 12 bolt housings becoming more and more of a problem, does that qualify me to install an aftermarket nine inch under it? I think of our buddy Aubrey Bruneau with his 4 speed 409 Chevy Bel Air bubbletop who could really benefit from that. The fact that Ford doesn't and hasn't produced those rear ends for 30 years or so,and aftermarket suppliers are now supplying them to Drag Pak and COPO racers under their factory race cars,(which are themselves outsourced),does that constitute a loophole through which they could be legalized for other applications? Just a thought on a boring cold night.
