Can’t quite tell for sure on the pictures, but like Glen said, the shins may be on backward. There’s a specific curvature to most kits shins. You can see above how the inner shin has more of a dip inward in the curve following the natural calve muscle. The outer shin has more of a natural curve from top to bottom following the natural curvature of your calve/shin as well. Just worth double checking that. You can trim some of the return edge off. I wouldn’t trim all of it. Here’s mine for example prior to glue and sanding: Sent from my iPad using Tapatalk
