Expansion Plug Set

[RoyLuke]

I am rebuilding a Disco 1 4.0 engine. Where can I find expansion plugs as a set. I contacted the usual sources and they want to sell the plugs individually.
The last time I did a rebuild I was able to get a set but can't remember where I got it from.

What are expansion plugs? Do you mean freeze plugs? If so, just google "rover V8 freeze plugs." Many results, many sellers.
