Is there an O Ring chain that is a direct replacement/fit for a 1975 Commando?

...and for a whole lot less money, I've been running this one on my '74for 3 years. Fit great.

I have also used this VX530 for my MK3 for several years now.
There is little space against the gearbox 1-2mm I think it was. But it is enough, I have not touched it, so it works fine

I guess they make 530 sealed chains narrower than they used to. When I was interested 10-15 years ago a 530 sealed chain would not clear the gearbox or the chain case (can't remember which). So I purchased the CNW 520 sealed chain kit. Been very pleased with it.

FWIW, I have never lubed that chain...or any other sealed chain. I occasionally wipe them down with a rag that is damp (NOT wet) with WD40.
