I can machine up a top plate and then just buy the universal straps from DJ and you are done/covered. Sometimes Tech has their own Ideas, no matter what the book says

A universal strap is just weaved into the top plate and adjusted to the proper length, the other end affixes to the bottom brackets as normal wheras the normal restraint is sewed onto the top plate and the length is fixed
