Okie,
I dunno if this will help you or not, but I floated my ProHunter forend using a piece of one of the Uncle Mikes Contender Strap spacers. I took the spacer, cut it in half with a Dremmel (Thank goodness for Dremmels'), then with a file (because pro-hunter barrels don't have bolts welded onto them) I contoured the one end to match the barrel,.....then I "Gooped" (glue I got at the Home Depot) the spacer to the forend.
Here is a pic....which is worth way more than my explanation. I hope this helps:
