Boot gas struts

[HPsauce]

I'm sure there's some information about this on "the other resource" but its down at present, so....
My boot is getting heavier to open, though it will stay up if fully lifted, so I think one strut is failing at least.
Does anyone have a known source/specification for these and are they different to the bonnet?
Also any tips/techniques on the process to swap over would be very much appreciated.

If you like bling D3 ones are the same but shiny

Nice.
How much and where from? And does anyone have the part number(s)?
