Heh... Yea... Doing a conversion from one to another generation sure can be nerve wrecking... I too experienced that when I did my OKMO 2A7+ one documented on Imgur imgur.com/a/GzLRqvl ( can't post links, yet )
Sawing off that rear portion of the turret sure as hell was a "press [F] to pay respect" moment and the darn DMD-T07 would not fit after that necessitating a modding of its casing and later total 3D Printing into a better shape to satisfy my needs of lowering its profile even further.
