Is the fiber glass A/C box on the fire wall next to the fender well, the same as a 69 Big Block I have found one for a 69 BB but do not know if it is the same and the guy that has it does not know either. I need one for 68 BB car. Thanks
The half next to the fender is the same for all years. The side next to the engine is different. All big blocks are different than small blocks and while the 68's are not physically different, the location of the heater resistor location is different. A 68 will have a 1" square hole in the top about 2" from the outer edge of the box (closest to the radiator). A 69 will have a circular hole closer to the firewall. The blower motor relay mounting locations are different to. The 69 housing has the relay closer to the outer edge, while the 68 has the relay mounted near the firewall.
