1973 Q code Mach 1 blue glow, 4 speed
1973 H code Convertible ivy glow, FMX
Got my exhaust manifolds cleaned up in preparation for installation back on the engine for my Mach 1.
RH: D0AE-9430-G with casting date of 3F19 (June 19, 1973)
LH: D1ZE-9431-BA with casting date of 3F23 (June 23, 1973)
This car was built 7/5/73 so these casting dates line up nicely with the build date of the car.
The RH manifold apparently had a tendency to crack over time so I was happy to see that mine had no evidence of cracking. These manifolds are in amazingly good shape for being 44+ years old.
