I have a question regarding the 1958 Buick wiper system.
In 1957, Buick installed the vacuum pump at the end of the oil pump inside the pan. Just where is it for the 1958's? From the photo of a 58 Buick engine bay as shown below, it appears to look the same as the 57 setup with vacuum lines as well but the windshield washer jar moved over near the master brake cylinder.
I ask this, since I am told the 57 setup was a one year gig only and that 58 did it differently since the "pump n da pan" idea apparently did not work out that well in the long run.
Did Buick go back to the dual vacuum fuel pumps or did they have another way of increasing the needed vacuum to necessary to accommodate the needs of the wide swept Cam-O-Matic wiper system.
Any insight on this would be appreciated.
