That would make the # read 981348 which does NOT show up in my 67-75 Firebird MPC.

The "strike" could be taken for a 7,which would give us 9813748 which does NOT show up in the parts book either.

981148 DOES,but it's tow ball (trailer hitch accessory)

P/N listed in parts book is Group # 12.966 Rear end finish panel assembly 9851259 1970-73 ALL F.
(I am assuming this is the plastic one)

I just looked at one and found the same "strike" over the number.

On another note- two more possible unique items

1)OPH said on another recent thread that 70 had an odd length yoke on the driveshaft.
2)What about the vented gas cap? 70 only?
