Where did you buy them? I wouldn't trust random sellers on Ebay, they're often just generic "SG style" pickguards that would be lucky to fit any specific model. A legit pickguard maker like MojoAxe or PickguardHeaven will have already created a template from a real '61 Reissue pickguard, and Gibson does not allow enough variation in their pickguards that it would not fit another '61 RI. And what a difference it makes! Those are the exact mods I would have done. Except maybe change the Kidney buttons to metal Keystones.
