What is the correct timing gear cover and valve covers for an early HIPO mustang with a 5 bolt block? The car is a June 1964 production. Specifically, which of the following three types of timing gear cover did it originally have?
Type A: Timing cover used to run an aluminum H2O pump and has an oil filler tube and oil cap sticking out of it.
Type B: same as above but has a plug pressed into where the oil filler tube and cap could have been installed.
or Type C: The one found on a 65 hipo running an aluminum H2O pump without any provision for oil filling thru the timing gear cover?
Also, are there any differences in the valve covers from early 64 & 1/2 to the ones used on a 65 hipo? Thanks in advance for helping, Paul.
