Width?
Theyre same except of piston pin size that you mentioned

Yes you are right but I dont know why is that. Don't buy those

Interesting question
i made this mistake once but i didnt understand which engine does have the smaller width and why
I dont see why the whole rod needs to be less width only because the piston/small end is smaller in width

Center to center length: 144mm/5.67"
Big end diameter: 50.6mm/1.992"
Small end diameter: 19mm /0.748"( tapered small end)
Big end width: 19.9mm /0.784"
Small end width: 19.9mm/0.784"

Center to center length: 144mm/≈5.66929 in.
Big end diameter: 50.6mm/≈1.99212 in.
Small end diameter: 20mm/≈0.7874 in.
Big end width: 24.9mm/≈0.98032 in.
Small end width: 24.9mm/≈0.98032 in.

Difficult to source H-beam rods with tapered 19mm small end and 24.95 width.
I can only find those rods with wrong width measurements.

Correct rods but with 20mm small end is easy to get.
But I need to get new pistons with 20mm piston pins.
