Title says it all.  Trying to fit a full size pulse set on my 104UB.  Gutted a novatouch and picked up the extra sliders to complete the set, but the bottom row is posing the problem.  
I had to accept that I wouldn't be able to use the pulse bottom row keys and swapped in a few of the blank keys from the pulse ergo set and a few novelties to flil out the different sizes for the modifier keys.  However, the length is different so as you can see I tried to cut out the sides of the adapters to make it fit, but the spacebar just gets stuck in place.  
For now, I have the longest ergo key as the spacebar, which actually isn't bad.  But for looks, I'd really like to make that black pulse spacebar fit to finish this mod.  I tried /r/mechanicalkeyboards, but couldn't get much love.  I know they are mostly cherry MX users, so you guys are my last hope.  I guess the only other option is to put it one without any stabilizers, but we know that's not really gonna work.
Thanks in advance folks and enjoy the feels
