okay I've had a rethink, the overall aim here is to be able to mount two bodies side by side to try and create a nasty trracer.
I've a disgustingly ugly solution for the trigger group of placing two existing trigger groups unmolested side by side with a gap to account for the extra width of the bodies, then attach a trigger by getting a longer trigger pin to go all the way through the two existing triggers and through the new trigger in the middle. a bar attached to this new trigger to pull the two existing ones. I aim to mount a grip between the blocks that the old grips attach to to hold it all together and give the correct spacing between the frames.
I'll get more use out if it open class so any ideas on converting from right feed to left for one of the bodies?
