These will help, too.
My first NF actually had the melted ramp floor cut out, and a new piece of lexan glued in place. Worked sort of, but was really, really ugly.
THANKS HEAPS JOHN.
I will order these for sure. If i order the new ramps etc and i dont order these protectors, the new ramps will suffer the same fete as the old ones did.
These look quite good as well. Thankyou.
