How to identify which pointy model from subframe

[Bunkle]

Could anyone offer some advice as to how I can identify which pointy model a subframe and plastics are from?
Will try and post pics but are there any obvious ways to tell?

Cheers,
Dave.

I know the subframe on the sk3 model is different. The subframe was lowered from sk4 onwards. It was made of aluminium too.

Cheers for the info bud.

I'm not sure how the plastics changed. The black infill panel on the right has a bigger cut out for the brake reservoir on the sk4. Also the toolkit was moved from under the seat and put in a container under the battery case.
