Default forged conrods

Please, is it possible to fit these conrods to oem BP-Z3 engine pistons (10:1 cR) without any modifications?

H Beam Con Rods Rod for Mazda MX5 MX 5 Miata B6 BP 1 6 1 8 133mm Arp 2000 800HP | eBay

the rods dimensions:
-C-C length: 133mm
-Big End Diameter: 48mm
-Pin Diameter: 20mm
-Big end width: 21.84mm
-Small end width: 21.84mm


Seller wrote me: "Our rods can't fit wrist pins on oem pistons but only floating pistons.If the dimensions are the same, please turn to a qualified mechanic for help to look for a floating piston and fit them on your car. It's a not difficult project only if the dimensions are right"

Is it true ? I was thinking that oem miata pistons are floating pistons. Not wrist pins pistons like seller wrote me.

Thanks, so both should fit without pin modifications to stock 10:1 pistons.

I've run ebay rods with 10:1 2001+ miata pistons, they worked great.
