I messed around with several different extensions. the factory ones leaked...then I went with some rigid ones. They are all finicky...the push rods can be a bit too long...or too short....or bent... or too narrow.....or.
Eventually I removed the wheel simulators permanently. Wish I'd done it right away.... removed all of the extensions and now can get at everything through the handholds with standard truck chucks and gauges
I used to use a pry bar like this one to remove my simulators
