Anybody who rides in the thickets of the deep South will appreciate having the shrouds held on with grommets, instead of bolts that pull thru the plastic.
Perhaps ... it turns out the grommets get hot (attached to the radiator) and soft ('cuz they're hot) and what was a firm fit in the shop is now pliable and easy to pull out. I'm trying to gin up a method (as are several others) that preserve the grommets but still retain the shrouds.
