Slant Six Oil light coming on — need a new pump?

prolly a small one on the top and bottom, Not a lot of wrench handle swingin' space, Just enough to get it unfrozen from the pipe threads. Once you get it started you can use a 15/16 o1 1" socket to get it the rest of the way off.

Now if this slant were in a C body or a B/D series van or truck thats' a whole 'nother level of working space.
