Main Gin Mount recoil unit and pivot relocation.
First I shortened the Clark Recoil unit by approx. .250” actual measurement is closer to .240”. I cut back the HL mantel adapter/attachment piece. I trimmed it expecting the main pivot boss of the recoil to fit into it more. I should have measured three time before cutting….I can work with it.
By shortening the main recoil housing the inner sleeve would either have to be shortened by a similar amount which would also necessitate either deepening the bore for the barrel to fit into or cutting back the barrel neither appealed to me. I finally determined that I could enlarge to opening in the HL mantel adapter which allowed the recoil inner sleeve and barrel to remain unaltered.
This also provided the additional 2-3mm needed for prototypical barrel recoil distance and then some. I will actually have to shorten the recoil distance I have using a stop of some sort.
Here is a photo showing where I have been adding styrene to extend forward the yoke towers for the pivot relocation, .250” further forward. It is proving to be a little more challenging than I first envisioned. I have also determined that the pivot needs to be lower to cause the mantel fit to the top plate of the turret to be more accurate. Unaltered and the top of the mantel will sit too high with respect to the top turret plate. I will have to hinge the close-out plate that is attached to the upper aft edge of the mantel as on the actual tank.
I will also have to shorten the mounting "posts" for the adapter to mantel to compensate for moving the pivot forward, mantel protrudes beyond the face of the turret too much now.

Thanks for looking,
