I have a question about the bolts on the water pump on my 1964 Sedan De Ville. In the shop manual it says not to install screw D, I am not sure why ( I have a non ac car) so is it because there is another attachment that goes on later in the installation on a car that does have ac? Also is the D longer than the C bolts? ( using fig 7-3 on page 7-5) Thank you
The "D" bolt is 1/4" longer because it is the only one that goes through the oil filter support bracket. This is the same on AC & non-AC cars.
