Hey C looks good
How did the panels ship .. any dammage ?
Please make sure the rad holes line up before you throw any more coats on
Just in case they need adjusted .... Kinda done on a wing and a prayer not having the actual unit there. I usally make card board templates of that many fixed holes due to having to free hand everything as I do not have a drill press and proper machienery
the two holes that were added from the OP are for the push pull fan wires
and the notch in the front is to accomidaste the tubes according the the diagram
Best of luck hope you like it ......
