Michael, the Silvers pads Galazan has are the ones in the link you posted, at least they come in a very similar package. I like them better than their "Period Correct Pad" from an installation standpoint, but they offer little in recoil reduction. Hard as a brick. About half of the Period correct pads I've installed have had a soft black spacer that regardless of washer size for the screws will lift away from the wood when tightened down. Each time I find one I call Galazan and they send me another for free - no complaints in the customer service, it's just unhandy.
will get the G&H on the way.
