Well Im at this stage now. The recoil mounts are in two of the tanks now.
The round perfect scale turret is a serious pain in the ass to work with. Getting the mantlet mounted and the recoil set up and lined up was a serious pain. The details on the cast turret are pretty rough, overall, I wish I had known about the Der Emma Laden turret, he makes a nice 3d printed turret with brass bustle rack. AFV model has an even nicer black resin 3d turret with tons of super detail brass castings but the price will blow you away. Its not really affordable.

The welded turret will be an AS1 which is an Aussie A3 variant. I used the Der Emma Laden recoil mount in it. Sadly, I guess it was desinged to fit into the older turret design as this is the 2010 static release and it has rollers in the bottom of the turret the original clutch and remote motorized did not. So it didnt fit, I had to hack it up alot and modify the heck out of it but the bracket and recoil was still easier than desinging my own system like I did in the 1a7 LEXMAS MEXAS2 tank I built as an experiment.
The rollers are 2x7x2.5 nylon same as used on the super sherman. I fought with setting this thing up for hours last night but finally got it to where I think I am happy with its position.

I havent gotten the transmissions installed in the 3d chassis yet. I will get to it eventually.
