Thanks for the info. That site is an excellent resource that I can use
for other things, as well. It looks liike I will have to get to these
from underneath, but the ramps I have are too steep, so the nose of the
car hits the ramps before the tires. As soon as I can get the car in
the air safely, I'll try to use a screw and fender washer to get them
back in place.
