H&R/Koni Yellow Combo

So I recently received my Koni Yellows and tried to install them on my car, but unfortunately my current coilovers didnt fit! So I decided to go with the H&R Race springs but I still face a problem, the tophats I have wont slide onto to damn Koni's
So my question for you guys is this, what tophats should I look into getting for my setup to work/should i just drill the one I have out a little bit? All second opinions would be greatly appreciated!
ps, i already looked into the GC tophats but they only work with the Koni/GC Combo.
