First time poster here, just wondering if anybody knows what size socket or spanner is required to loosen a very tight/stuck band adjustment lock nut, I only have metric and need to get SAE or imperial I would presume, the previous owner or shop have slightly rounded the edges removing it in the past it seems. Also would it be preferable to get a new nut after loosening it or just snug it back down once adjustment is made?

If anyone has advice on socket size or a specific tool available to loosen it as the space between it and exhaust is very tight I would be very grateful.

The nut is a sealing nut and has an attached rubber seal. They are really a one use nut and its recommended to replace them. From memory a 3/4 inch spanner is used.

Hey Lyle,
If Andrew's right about the size 3/4", that's 19mm exactly, within hairs!
Don't go and buy a spanner or socket.
Cheers Phil.

You own a classic mustang and you only have metric tools. If your going to do any work, seriously, buy some SAE tools thats what they are made with.

Thanks AussiePhil, will give it a tentative try, as I said it's been rounded a bit, just don't want to make a bigger mess of it. If it doesn't work I'll definitely look into a set of sae sockets or spanners FB or last resort take it to my mechanic to do it (old school guy whose worked on numerous mustangs plus other classic models so in good hands), just trying to become a little more self reliant with maintenance and repairs.

Hey Lyle.
I agree with FB, get yourself a set of AF tools.
Don't go crazy.
Don't fall for the trap it has to be Sidchrome or Snap-on, Kinchome, JBS, Stanley and others make lovely tools also.
I've bought some really good tools on eBay auctions.
Cheers Phil.

Thanks Phil, successfully removed it last night with a bit of swearing and have a new on order, 19mm ring spanner was pretty much spot on for the size. I agree on the tools, it'll be a slow buy process, buy as I need so to speak.

Cheers everyone

Glad to hear you're giving it a go! It's always smart to start with a tentative approach, especially since it's already rounded a bit. If things don't pan out, a set of SAE sockets or spanners could make all the difference; they're essential for classic models like Mustangs. Having a reliable mechanic as backup is reassuring, especially one with experience on older Mustangs and similar classics—sounds like you're in good hands. It's great you're aiming for self-reliance in maintenance and repairs, and every small step builds confidence and skill.
