Spanner sizes

[EggsBenedict]

I thought I had just about every tool I'd ever need, but no, it seems.

Anyone know the correct sizes for (1) Rover V8 sump plug (Chim 400 stock, if that helps) and (2) BTR diff filler plug.

Thanks!

Ben

1: 1 1/8
2: not a clue (and don't have one on my car to check)

thanks! Got that first spanner off the 'bay. Hopefully someone else can clue me up on the other. According to Mr Heath, the BTR diff oil is supposed to be changed every 12K miles, so someone out there must have done it and knows...
