Hardware for your jet pack??

I was wondering what everyone is doing about connecting there jet pack to there out fit?

More specifically im wondering what your using on your jet pack? Ive seen people use a metal plates thats screwed in the pack... But i have no clue where to find them or what to use?

Im running a MOW pack.. and suggestions would help out alot.
thanks

I'm thinking about getting some 1/8" thick sheet metal from Lowes and see if I can cut and bend it to the more screen accurate shape. I am using 1" stainless steel loops from Strapworks.com to hook my JP on.
