I am mounting on a Ben Mears "Fighting Buck" form. The cape, and I have tried 2 capes, will not fit at the shoulder area of the form where it mounts to the wall. I lack about 1 1/2". I have sanded all that I can without loosing definition and am pretty much down to the rear plate on the back. My question is..."are all forms close to the same size at the wall plate? I have stretched, sanded, and pulled all that i can. everything else fits fine. If i ordered the next size smaller in the same pose, would that dimension change? I am not a pro by any means (this is the 6th deer I have done), But all my others have turned out really nice. I'm open to all suggestions.
