Ok...Thanx for your input!
I have found this table, with these axle codes added:
(all were for the NOVA application of 1970)
CPO-"Heavy Duty"; change COC to CBQ; new codes CBI, CPL, CPM, CPT, CPU
************************************************** **********
The chart attatched provides what codes are known...
The Camaro codes seems to be in the COA-COZ & CRA-CRY order, so if you suggest a CBE, this would be...?
