So first off you should stick your grips on your frame.

Then your gonna wanna take a dremel to cut off the top and make it match. I Used the sanding bit for this.
In order to make the grips not look all scratched up your gonna want to lightly sand out all the nicks from the edges of the sanding bit, then your gonna wanna follow the procces i mentioned before, where i used 400 grit sand paper and then 600 grit, and then 600 grit wet, and then buffing.
Heres some pix of what i did to my grips.

The red in this pic is from the polishing material goo stuff i used 8P

Dont wind up shaving it too far like i did here...
Now for the time consuming part, grinding out the insides for the board. Remember the amount of grinding needed depends on what board u have. For the yakuza oled cocker boards you will need to do a lot of grinding. IMO you might be better off using just a stock e2 board.
Now the first thing your gonna wanna do is cut off a piece of the frame on the right in order for you to beable to put your board in. I used the fine cutting blade for the cutting.
Heres a pic of what were cutting.

Heres a pic of it cut off.
After you’ve done that your gonna have to do a lot of grinding on the inside to get the board to drop in. Its really really hard to grind it out right and get the board squeezed in there so please be as careful as you can because I take no responsibility for anything you may break while trying this. I chipped my optical eye trigger switch, but luckely it still works.
Heres the grinding pic again.

Heres the grinding ive done.

But be careful not to do this 8P

The main grinding needing to be done is just for the little black barrel shaped thing on the board. Its on the top left corner. Becareful cuz some boards have diff sized ones, and idk if a yakuza oled board will fit in their comfortably. And then your gonna need a little bit of grinding near the back of the trigger on the inside of the frame, cuz the board is a bit too wide.
Now that the board fits there two thing left to do, other than some finishing polishing if you havent already done that. if you try to fit the board in make sure the trigger is not in the frame, it will get in the way.
Heres a pic of the trigger carier. And what you need to do to it.

This is only if you have the 3 way solenoid on the front of your cocker. But that will apply to almost all of you.
I used the fat black grinding/cutting disks for cutting it out.
Since it was my first time and i wasnt paying attention cuz i was tired, i cut the trigger pin and one of the bearings. Make sure you take these out or be careful.
Heres a pic of it after.

Keep in mind that its gonna be a tight fit, and it makes it easier if your remove the black rubber tubbing on the solenod wires. I just used a razor blade to get it off. Also if you mess up the trigger carrier you can cause a lot of side to side play so be careful. Dont make it looks the way it does in my picture.
Once that is done the only thing left is to make the trigger fit.
The trigger needs to be shaved down on one of the sides, otherwise it rubs up against the board and the trigger wont move freely.
*edit* You may also need to grind down the back of the trigger. Where you will mod it to set off the optical switch on the board. If you do, the trigger will stick, because it is getting pressed too hard up against the optical switch.
Yes the trigger can touch the optical switch so be careful so that it does not, and you do not break it.
Heres a pic of the grinding i did so you can get an idea of what you need to do.
Now in order to allow the optical trigger switch to work, your gonna need to put something onto the trigger to go past the eyes on the board. I saw some one use a piece of plastic, but i found it to be easier / more reliable to use the cut off end of an allen wrench.
Heres the pic.
Once your done with that you should be done and your sexy looking marker should have the frame fitting onto it nicely like mine in these pics here.

Enjoy 8 )
