I checked the data plate on the one I am interested in restoring and it has 511-DF-5 in the model section. In the serial number it has 28551 GT
The other pump has F-5 in the model section but above is also 511-D and 19822 GT.
Thanks everyone for the info.
I'm sure I will have a lot of questions as I get further into this.
I am guessing the these pumps were updated and changed many times over the years of use.
And who ever had these has added parts the make them more complete.
I will check out the links that were posted
I am most likely to try and make it look correct for the 1969 to 1972 era as of now.
Thanks again
Dave
