Side mount seats - standard mount points?

[Herman Toothrot]

I have a Cobra seat that has both base and side mounts and I had been using it as a base mount, I'm changing it to side mount. Do I have to buy Cobra side mounts or are side mounting points standardised so allowing any side mount plates to be used?

They vary. There are some "univeral" side mounts around, but personally I'd use Cobra ones for Cobra seats if possible.
