I ended up putting my switches in a MUD dash pod

Just a word of warning about the item in the picture, i got one of those to install in the back in a custom shelfing box...
All sorted now.
I ended up only replacing about 10" as the rest of the pipe was in good condition, just the bit where i spun the nut into got damaged 🤣
I plan on getting the body off later in the year so i will do a full job then.
Thanks all...
