I scored a set of billet main caps, just the two centers, for my new 109 but they are machined for a girdle and I am not going to use a girdle. I'll be using studs and a steel crank. My question is: any strength lost from being machined flat for the girdle? I would think they would clamp the same, but if there is strength lost from the meat taken out, then I'll get new ones. TIA.
