When replacing Judith’s chassis we had to go with the front bump stocks that were on the shelf. These use hold the rubber onto the mount with folded metal [shown on the left below] which isn’t the best method (although it’s cheap). The better option are the bonded bump stops from ECAS [shown on the right].
This borne out by the fact that the near side (why is it always the near side) rubber had fallen out on the old bump stop.
Access to the bump stops is pretty easy, with the front of the car jacked up the swing arm clears a reasonable amount of space and, once you’ve worked out the best angles of attack, I found they came out with minimal persuasion – although a small pry bar was really helpful with this.
With them coming out so easily, fitting was the reverse of removal: finagel the bump stop bolt into the hole in the chassis plate and do the nut up to the standard torque setting of FT.
