Theres stil lots to work out from my end on the PD as I've only replaced certain parts, re sizes aside from the plastruct lamps it all depends on what sizes you use for the legs. As far as I know there are 3 sets of these, Mine Lees and Moes, and all 3 use different size
ABS for various joints. I would recommend getting
ABS stock from 6.4mm up to about 16mm in the rectangle stuff and go for your own methods. The U channel you need will be sized depending on the size of rectangle tube.
Re lists, I dont have one but just copied what " I" used on my last set. These do vary on current builds though so it is best to go your own way or I could send you down a dark path. I dont have the codes in my head but used the info in Lees thread for the lamps. I'll try n dig out my plastruct order from EMA
