If the screws go through the spacer why not just leave it there and attach your new recoil pad on top of it? I had to buy two Tikka spacers for my T3 lite due to having arms like an orangutan at £40! You might find it fits nicely without the aggro of trying to remove it. As for replacement pad, I’d recommend a Simms Limbsaver, really good especially if you’re firing more lively cartridges.
