Cool, those would be helpful.

Now I'm trying to decide if I should make a fancy dual spring compressor or a simple single one.
I don't have the dimensions for either one, I might just pull a cover and get some measurements.

 

Just make a single one. More than likely you'll use the tool only once and forget where you put it You can even borrow my ghetto one I made if you want. It's a lever type one that I cut the handle off so it would fit on a lsx head. I then stack spacers with it to keep it stable and to have even pressure across the retainer.
