Rolex Day Date Dial Measurements

I've been toying around with a 18239 build for a while on and off and have adequately screwed things up a couple of times so I am looking at making certain things easier for myself by making a Day Wheel Overlay tool. Currently taking measurements off of a Rafflesdial 28.5mm dial but I am wanting to make sure that the tool is usable with as many dials as possible.

I assume this could only be done with 36mm varieties of the DD due to the day display location.

Does anybody have any proper measurements for these dials or more importantly the dial feel locations for genuine day date dials as I do not have one at hand? Below you will see the measurements that I have so far been able to estimate.

Thanks in advance

The gen movement is 3155/6 or 3255 in the 40mm. The feet positions are exactly the same as the 3135, so if you can get a hold of any of those quite common rep dials or movements, that would give you the feet positions.

Okay, so far I have been able to track down through eBay listings that the dial feet position of the 3055 and 3155 movements are at 10:30 and 4:30. Will have to look further regarding the dial feet width and distance from the centre point.

OK, I see now that those feet positions are different from the 3135, sorry about that. The 3155 is based on the 3135, I wasn't aware the feet positions were different. It might be a while before someone can help you with the other measurements, it would be rare for someone to have a gen dial not installed in a watch. I'll keep an eye out.
