COPO 9511

[Nova Research Project]

More clues,

In 1968 (as of Jan 1868) the 3.73 for Nova has an RPO of H05. The 4.10, 4.56, 4.88 were listed but with a * to indicate they were only available in a Posi.

Again in 1968 the instructions in the dealer catalog stated there were three optional Ratios for Axles:

All for $2.15

<span style="font-weight: bold">Axles Rations:</span> See Power Teams chart for availability
<span style="font-style: italic">Economy</span> AXL1
<span style="font-style: italic">Performance</span> AXL2
<span style="font-style: italic">Special</span> (If axle ratio other than Standard, Economy, or Performance is desired, refer to Power Teams chart for availability - then list ratio on order form in box under &quot;Special Ratio&quot

While in 1969 the same section lists:

<span style="font-weight: bold">Axles Rations:</span> See Power Teams chart for availability
<span style="font-style: italic">Economy</span> ZQ8
<span style="font-style: italic">Performance</span> ZQ9
<span style="font-style: italic">Special</span> ...

Again in 1968 the dealer catalog listed the 3.55 as standard on the L78. <span style="font-weight: bold">However</span> in 1968, Chevy listed the 3.73 (H05) as the Performance option. In 1969 there was no performance option listed. In 1968 the Special options were 3.07, 4.10, 4.56, and 4.88. While in 1969 the only Special list was 3.07.

In Summary, the specifications list all rations in both years. From a customer or salesman point of view:

In 1968 you can easily see the options and then write them on the order form. I.e. normal process.

In 1969 you could not see the options, but you could write them in on the order form. Would this trigger the COPO process?
