tips on fitting now boot gas struts

[3.7 slp]

Hi all

Hope that eveyone is well, just a quick one to check as my gas struts for the boot have given up on me . This has made the opening and closing very heavy not good with a full hand of shopping bags as was found at at Tesco.

I have a set coming from the great team at A8 parts...lifesavers as they are about £80 from TSP..
....How easy are they to fit would anyone know or have a guide on this...

Thanks very much all
