Rouse Tech 29MM Aft Closure Dimensions

I have a 29/40-120 case on order. The after closure appears to be a slightly larger version of the 24/40 aft closure. The longer 29mm cases appear to have a different aft closure design than the 29/40-120. Can someone give me accurate dimensions on the OD and length of the knurled portion? I have a thread aluminum retainer I machined up for my 29mm rockets but didn't realize the aft closure on the other cases was so different. I want to see if it will work before I buy one and have to redesign the retention systems.

The Fwd and Aft closures on the 29/40-120 DO NOT fit ANY of the High Power style 29mm cases. NONE, NADA, ZILCH, NOT HAPPENING

The aft closure on the Hobby Line 29/40-120 aft closure is 1.230" OD X 0.250" in length while the normal Aft Closure dimensions for the 29 mm High Power Hardware is 1,250" OD X 0.368" in length.

Keep in mind, the 29/40-120 cases are different than the other 29mm cases (29/120, 29/180, etc.). The aft closure on the Aerotech 29/40-120 isn't knurled, it has slots in it to be used with their special wrench. I haven't seen a Rouse-Tech 29/40-120, but I would imagine it's the same. The wrench fits both the 29/40-120 and the 24/40 cases.

I wasn't writing very clearly I guess. I know the 29/40-120 hardware is different form the normal 29 millimeter hardware. I am not attempting to mix the two. I have a retention device that works for the 24/40 and 29/40-120. I wanted to know the dimension of the HP 29mm after closure because I knew it was different. The drawing posted above had the dimensions I needed.
