Why would they just give you the info when thats the type of info some get paid for...?
Because that's what these forums are all about. Sharing information and helping each other do things on their own. Tom and Josh over at Jet Boat Performance do boat work for a living and are more than willing to answer questions. It's not always about the money.
Here is a post from my thread on this subject, with great pictures.

The four across the back (right hand side in the photo, again I think 5/16" on those) hold the rideplate to the shoe and continue on through to threaded holes in the intake. It's a sangwich. I believe there are three shoes (some say four) to choose from depending on what you're trying to accomplish. Mine's a backcut (in the pictures), there's a flat (what's on my other boat), and a tapered. You'd have to consult with someone who knows how it all works, but I believe the backcut is designed to raise the whole boat, The tapered is to get the bow to ride higher and not necessarily provide lift to the back. The flat I have no idea. I'm running a flat in my other boat, but have tried a backcut and found no significant difference between the two.
Hope that helps some.
Shoe and shim removed. Note the countersunk hardware.
The area that needs to be machined for the shoe and rideplate.
Shoe and shim flipped upside down to show how the bevels have to mesh up with one another.
And one more picture I got.

Just to add a little more information. Here's a picture of the whole works assembled since the above photos don't show how the rideplate fits into the deal. Don't mind the missing bolts in the shoe. I have to pick some up.
I've also been informed that the shoe pictured above is a "closed edge" shoe. Not sure what exactly that means, but there ya go.
Thanks for your input everyone. It seems I will have to get a shoe and figure out how much to machine from there. I understand no one wants to give away thier secrets. i just thought there was a standard procedure for doing it. Thanks. John.
Heres a diagram from American Turbine for Dominator Intakes (works well on Berkeley intakes also). These measurements will alow you to use off the shelf shoes, or if you plan on making your own it should serve as a good guideline
