B4 seat upgrades

[fonzooorooo]

So... I know mk3 golf seats are a straight swap, and that b3 ones are the same... But what else fits straight in?

I wondered about 6n polo (fronts) and audi 80 (again, mainly fronts, but rears would be nice if it's a viable option!) but haven't taken any measurements... Quite excited aout the prospect of getting rid of poverty spec CL seats!
