So, I poked around the internet. I knew that Micah posted a picture of this board on his blog/website when he was done shaping it for me.... This doesn't give you the exact measurements, but at least you can at least see the fin setup....
It's 5'7x19.75 to put it into perspective.....

You should definitely put some center plugs in it. Can be something fun to do on a flat day. It's just a surfboard. Your not gonna hurt it.
Make sure to wipe (where resin will contact) the plugs with acetone first, or at least sand em a little. Glue sandpaper on the jig you use to drill holes so it's less likely to move. Hold that thing tight.

I'd guess the trailing edge of the front fins are set off the tail somewhere around 10 3/4" and 1 3/16" or 1 1 /4" off the rail. If you set the center fin too far back (3.25) on a wide tail and the cluster is too spread out, it can get a little tracky. But if the rails are kinda tucked in the tail (plus softer forward) you can get away with it. I'd go up...maybe 3.5 or 3.62.
I just shaped a 5'9 x 20.5 x 2.5 small wave board with a wide squash and soft, low pinched rails. The fins are 1.25" off the rail and 10 13/16 from the tail. The center fin is 3 5/8 off the tail. Pretty standard placements for a wider small wave board. Thing goes insane.
Standard HPSB in the 6' range fin placements are 11" from tail x 1.125 off the rail x center fin 3.38 - 3.5 off the tail depending on amount of vee/flip in the tail.
