Not sure what you mean about a 4 or 3 pin lock out valve body.
To swap plates and valve bodies around there are a couple of holes that need to be matched up. Depends on if there is a converter clutch shift valve in the valve body or not.
This would require photos to indicate which is where.
Some people are like Slinkies... Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.
