I have a stahlbus. I thought about cutting an access panel into the bash plate but I quite like having a good look around while the oil is draining. Now I have the right bolts on the bash plate ( all sorts of dodgy and missing crap when I bought the car ) I now have a little routine. Spin them out with the rattle gun and it’s off super quick, they go back in with fingers to start the thread and hang the plate, and then a quick buzz with the air ratchet to do them back up.
