K series R500 piston rings for Cosworth pistons

Doing a refresh on my K series R500, I need a set of piston rings but struggling to find out what Minister fitted. Can anyone advise ?

thanks
Andy

If they are Cosworth pistons then I guess you have enquired there? It’s probably a standard Cosworth ring pack of the relevant bore size?

I would ask DVA Power (Dave Andrews) - he's bound to know.

Bolter, bolter, full power...

Pistons were supplied without rings from Cosworth so unlikely these were designed to take Cosworth rings. CC are suggesting std K-series rings 1.0,1.2,2mm (which I can check) but haven't found  K-series ring widths yet .

FYI, the stock K series rings don't fit. A ring pack is on it's way to Andy.
