Dumb question. The rubber bumpers on the clutch and brake rods -- aren't the rods supposed to move through them? In other words shouldn't they be affixed to the firewall somehow? Or do they move in and out with the rods (that's what mine do, seems odd).
Can you trim the bumper? Or glue it to floor board with Contac cement?
The clutch pedal bumper should be narrower on one side, to just clear the frame rail. Bob Drake catalog has a good picture of it:https://bobdrake.com/products/1939-48-brake-clutch-pedal-bumpers?_pos=1&_sid=8f298bf9b&_ss=rIt seems wonky because the clutch bumper goes down and squishes kind of sideways against the frame rail.
That's what I was thinking. Or the black weatherstrip adhesive.
