Educate me please - 911/964/993 engine lid differences

[Orangecurry]

I know the spoilers are all different, but ignoring that, are there any differences between the shapes of the pre-996 engine lids?

I gather that the bonnets are all the same.

Are the fixing points different? I know that aftermarket hinges are different, but are the differences on the side where the hinge attaches to the body or the lid?

Basically - are the three eras of lids interchangeable?


I've done a search but the terms come back with too many results on buying the parts, not the differences.

Thanks!

Gosh yes how unobservant of me. So is the rear light bar that much lower on the 964?
