recoil pad ? for Rem 870

[twofifty]

I have a 98% Remington 870 (from the early '70s) whose original recoil pad I want to replace as it has lost some of its give.

I would prefer avoiding the downtime of a grind-to-fit, but will go that way if you think there are substantial benefits.

Can you guys suggest a brand of modern recoil pad that would be a decent fit on a wood-stocked Wingmaster? (Not a slip-on)
