This is a generic how-to, in effort to show anyone that wants to do such a mod how to figure out how to do it themselves.
Anyone who has experience on the matter, please post or PM me so I can add to the original post.
To start, here are the areas that need to be focused on-
1: Make sure the top of the frame and bottom of the body will match up. If they're not both flat, you need to either make both flat, or make the curves match. 2: The frame mounting holes must line up. This will typically require either drilling a hole in the frame (IMO, this is preferred) or drilling/tapping a new hole in the body. Pick either the front screw or the rear screw to match up with the existing holes, then decide how to drill for the other hole. 3: Make sure the board can fit. This may require some milling, filing, drilling, tapping, etc. Or, you can get a Scenario Dreams Universal T-Board, and it should fit in ANY frame. 4: If the gun is going to use eyes, decide whether you're going to make the existing eyes fit the new board, or the eyes that go with the board fit on the old body. This will usually require soldering.
If ANY of this sounds like too much for you to do, it probably is, and you're better off finding someone more qualified to do the job for you.
