[Mgs] MG Related - Sort Of

[frankk12 at verizon.net]

I purchased two sets of ramps to use for oil changes and working under the
front end of my MGBs. One set is steel and I got them at a yard sale after I
had bought a hard plastic set at Wal Mart.  The problem with both sets is that
when I position them in front of the front wheels on my shop floor and attempt
to drive up on them they slide forward. The only way I can use them is place
them in my gravel driveway which provides enough grip so they don't move.
Problem is that I am now forced to lay in the dirt/gravel for working under
the car and doing oil changes. Is there a way to keep the ramps from moving on
my shop floor when I attempt to drive my car up on them?
