[Amps] 3CX800 grid collet or SK1900

[Conrad PA5Y]

I have a grounded grid 3CX800 2m amplifier that needs some TLC. One of the most alarming things is that the grid is grounded by 4 small pieces of fingerstock that has seen better days.  I thought that I would remedy the situation and so I am looking for a grid collet or the SK1900 assembly. I have just moved to the Netherlands and as yet have not learned where I can buy suitable fingerstock that can be formed into a rig. 

Any help would be appreciated.
