rear of the pad.
2) Use a long flat blade

the rear of the stock.

Remington has 2 rear spacers for a long or short stock bolt. The longer
bolt requires both spacers. The Winchester does not require a rear
spacer. The Norinco 98 uses the original metric stock bolt, the platform
#SPG-0111, and the Remington Spacer #SPG-0114 must be cut to length.

fit Norinco 98 Series Shotgun)

To fit Norinco 98 Series, cut the Remington
Short Spacer as shown, then follow Remington instructions.

5) Place the stock bolt through
the spacer(s) and platform and install in the rear of the Pistol Grip
Stock. With the stock bolt extending out of the front of the stock,
place the front adapter over the bolt and against the stock. Place the
Pistol Grip Stock up to the rear of the receiver and secure by
tightening the original stock bolt.
6) Place the new recoil pad on
the rear of the stock and secure with the 2 screws provided.
