No I didn't try that. Interesting idea though.

With the old bellows in the way that might be difficult. You might cut the slot for the arm and then just cut off the studs to aid getting the old bellows out. With the old bellows out of the way cutting the liner/insulator might go OK. I think I almost got the new one in when the stud broke. The extra room provided by cutting the insulator might just make it work.

Pre-threading the studs by running the nuts on and off a couple times should be a help also. (Make sure it follows the same threads each time.)

Also, I was using a conventional drop light for light and its heat made the vinyl carpet backing out-gas and made me sick during the process. (Bad head ache and nausea!)

I need to get one of those nice cool florescent lights!
