I need to take my end cap off of my gearbox to replace the thrust bearing (which I already have) but have been advised that once the cap is removed it cannot be used again so I need to buy a new one,does anyone know where I can get one as I'm having no luck finding one so far.
It's a 1990 16v with a o2y box with green cap.
Any help would be much appriciated

Cheers
