Chevelle Question......

[Ed Cunneen]

Just for clarification, Copo 9694CB is the copo for a single piston type - manual design front disc brake unit. The CB suffix refers an order combined with a 3-speed automatic transmission together with Copo 9737 and RPO J50 Vacuum Power Brakes. Disc Brakes were a manditory option on these cars.

If the 9694CB is the 3 speed auto with disc brake why is the J52 option not on the vehicle import sheet option list, only J50? The Canadian documentation call out 9694CB as 3 speed auto equipped with power drum. I would expect that if CB combined the J50 Power brake, 9737 option and disc brake option, the J52 would also be reflected in the option list as the J50 is. The 9737LE option is listed seperately on these cars. Another mystery.
