Frank Rolex 1500 Help

[Patpat1377]

Well here we are, after looking for less than 15 mins on a frank rolex build post I've decided to jump on the train myself... Just one issue being I have no knowledge whatsoever on frank builds. 
People constantly tell me that there are numerous posts out there on forums but guess I'm just unlucky and not able to find them. Im hoping this will help numerous people with the task of building their first frank watch:

Where I am currently at with my build...
•Gen 1500 watch case
•Gen 1500 Dial
•Gen Crown (having issues with the threading currently,,, it seems like only one thread catches and doesnt screw completely down... Not too sure what the issue is)
•ETA 2824-2 Movement
•Yuki spacer for the watch
•Raffles Tudor watch hands
•AfterMkt sapphire crystal


Heres where I really need help:

Ive heard that the dwo has to be modifies in some way and im quite frankly unsure of how that works. I have the eta movement dial spacer which im hoping gives enough clearance but maybe someone can clarify

I'm also not too sure of the best way of going about putting the dial onto the movement. I do realize that the legs for the 1570 movement are diff from the 2824 and will have to be snapped off. Where do I go from there? Installation using dial dots?

Last but not least, the overall fastening of the movement to the case. I feel like this is sort of self explanatory but I'd just like to inform of myself the tasks that have to be done to accomplish this.

Someone please send help
