I understand the cup mounts to the dome and has the 4 arms that comes out of the cup The cup (alum.) Is threaded in all 4 holes for conduit The block has 4 holes. 2 are threaded(on sides) then conduit on top and bottom I can thread the t. Into the cup but the rest. I'm lost to as what the plan was to assemble it correctly
May look into removing the block The pics I seen of orignal blocks were threaded also. Maybe originally the conduit did not actually thread into The cup but just passed through it. To thread into the t?
Well found out. There is 2 differant styles cups. One is steel. The conduit passes through it and a nut 9n back side The other. Is cast alum and thicker. Uts drilled but also tapped. So the conduit threads into the cup and not the block that makes up the t cross So all I have to d9 is remove the alum block
