Hi Dave

When I put in my Nissen radiator I also had a tough time getting the
bottom mounts in, A normal tap did not help because of the point and the
taper. If I was to have to do it again I would look to borrow a  bottom
tap( I think that is the correct term, as they do not have a point )I
was scared I would puncture the radiator with the other tap. I used some
bicycle teflon chain lube in putting mine in. WD-40 is a great solvent
or rust inhibitor, but not much of a lube product.

ile installing the rubber mounts, I backed out the rubber mount, put anti s=
eize on the stud and screwed back, backed it out, screwed it back in.
