Exactly. After removing the 2 pin jack, I took a piece of scrap aluminum, centered approximately over the holes and traced the opening and screw holes with a pencil. Then all you have to do is drill some holes. The screws I believe are 4-40 which means use a 7/64 inch and the RCA is ¼ inch. For holes bigger than lets say 1/8 inch, I like to use a Unibit because it makes perfect holes with a hand drill and can even debur if you use it correctly.

All you have to do is remove the bottom cover of the AC-4 and you can easily make the measurements. The RCA jack you will use will provide the measurement for that hole. BTW, the kit that is being sold is an official Drake modifuication kit. 73 and Happy New Year, John, W4AWM
