Hi there currently trying to change my passenger side exterior CV boot and can’t get the drive shaft nut off. I know it’s a 36mm 12point and finally found one from Halfords after lots of searching and travelling to collect vs order so I could get it done quicker however it seems the socket I’ve bought, the rim of it is too thick to actually fit in the space between the Nut and the surrounding circle. 
Is there a specified socket or one someone’s used in the past that they know to work ? 

I've got a picture of the one I use somewhere I think, but can't find it.

Did find this that I've written on here in the past:

"The one I use is a shade over 48mm O/D, but measuring the recess it looks like anything under 50mm O/D should fit."

I'm sure that I bought a Draper deep impact socket - and that worked, though I've listed that as being a Laser Tools  0954  - can only guess that I have checked the OD of the Laser Tools offering and found it to be exactly the same as the Draper one I bought as Laser Tools tend to buy in many tools from other sources.

 

Bottom line, I knew that I would, some time, need to get these nuts off, so ended up at a tool stall at a market, and bought that Draper branded one - and it worked okay, on 2 cars over time.
