Steve,
I have to admit I have not looked at the nuts since it came back from you. I presume you replaced the nuts that were previously there, which from memory were 1/2" AF cadmium plated nuts, which when I changed the exhaust to a G56, were a nightmare to undo and do up. It was just one of the things I thought I should look at, when I get it out of storage, as there is an exhaust rattle and I was going to do an end to end on the "pipes" but it is probably the heat shields. The metallastic bobbins could also probably do with replacing but I have spares of those. I think in AF sockets I only have 1/2" and 3/8" drive in France, so I will take a deep 3/8AF 1/4" drive socket out with me. I do have a large 1/4" drive metric set with various extensions and both powered and unpowered ratchets.

The 3/8th drive will work just but you will need a long extension bar at the least.
