Have you asked the guy ?

I was watching them on eBay last year or the year before but the pistons dried up so I lost interest. I would also be interested in a set.

Burton power have the pistons at £300 but I haven’t checked if that’s plus vat.

pec offer the Rs spec rods but nearly twice the price and you may as well get forged pistons while your at it. Back to the Rs pistons. They are NOT forged.
