Like others, I initially thought that the ramps were there to accommodate the springs on full bump. But I don't see how the springs can rise so much that they hit the underside of the floorboards. Similarly there seems to be no way that the rear axle could rise to the full height of the rubber buffers fitted to the top of the steel hoops bolted on the chassis. I have decided not to include the ramps in my restoration - am I wrong?
I don’t have the ramps but the floor had been cut away to provide for them so we just screwed a flat covering panel onto the floor. This has the advantage of being easily removable to give much better access to the brake cable adjusters. Perhaps not so relevant with 12” brakes but it makes things much easier to get at with the 8” ones.
Perhaps trial drivers could offer some insight.My Stiles D has taper machined out the bottom of 7/8 ths board,two inches wide.P lansdowne still has them.
Sadly Omno the roads in the U.K. do not match those on the continent , certainly in towns and cities. The potholes and speed humps exercise the suspension to its limit !
Thanks, gents. Since the body tub of my car is original and has metal panels that include this slope, the new floorboards will include it—even though no trials are planned.
