I just fitted FLM40010 to my Savage Flux and the dogbones fell a bit short. They make horrible grinding noises and dislodge while steering once in a while. Since I've taken out the original flux cups (because they didn't fit the bulkhead) and put in FLM ones I'm suspecting (with the "XL" branding at the kit itself) I need XL dogbones. Am I right?
