I've seen the excellent work OBN and others have done with mods and endcap work. I have this kit of parts to eventually build an Excal. The endcaps look like they may have cracks. I am torn between using female M12 inline receptacles embedded in the endcap vs using black plastic Heyco's here with the strain reliefs (like original) and then use inline M12's 6" out or so. Probably less stress on the endcap using the outer in-lines. What do you think? I haven't decided on whether or not I'm doing the PP mod. At this point I don't even know if my coil or PCB work...
