Ok, then the setup you want is going to be different than mine. I would suggest buying a tmaiya recoil unit from the AAF tank museum and then making your own recoil stay to mount it to the turret. There is plenty of room inside that turret to make everything work nicely.
I know a couple of guys here built these tanks already...Perhaps C4Star will chime in. I think he used tmaiya electronics to build his leo.
