The ones tucked under the front "points" of the aft-hull. The molded-in ones got covered by greenstuff when I added my usual reinforcing skim-coat of greenstuff over the brass pins for the engines (it blends out all the way to the crease at the middle-third of the hull bottom). It's the same for all my old lead Klingons.
AH! I had forgotten that those would likely be lost with all the green stuff buildup to support the engines. I thought you meant the phasers replacing the disruptors, and couldn't figure out why they would be on the wings.
I changed my mind on the thickness of the "greenstuff" under the rear hull and Dremel-ed most of it off tonight. This is the third time I've re-done this portion. [sigh].
I also removed excess metal from the new engine and fitted it for pins, in addition to drilling the stand hole.
I went back and looked at the ship card again, and no, it looks like I missed the engine-mount phasers that replaced two of the disruptors.
I'll go back and look at the size of the disruptors to see if they are appropriate for single-mounts and then add a phaser to each engine with a dot of epoxy.
Added the non-weapon option hatch on the bottom of my rebuilt Federation War Heavy Destroyer with a tiny piece of brass sheet (trimmed from a photo-etch detailing set for a plastic tank model):
I need to go home and sleep.
