I want to modify a set for the 2002 X that do not have the holes for side adjustments and the lumbar lever. My understanding is that the holes are elasticized so you can stretch them over the knobs.

Here's the question:

I know I need to punch some holes in these myself to allow the knobs to go through, but can the knobs be taken off and then put back on once the "stems" go through the modified holes? If so, how do you take them off? Do they unscrew, pop off?

Since the modified covers will not have the elasticized holes, I'm thinking this would do the least damage to the covers.

Thanks in advance,

Lee
