Quick fan Q

I'm needing to know the size of slim-line style fan that will mount to a stock gvr4 radiator. Most commonly used, bolt on. Mines pretty busted up by now. The material the fan surround is made of just crumbles if bumped to hard.
A link would work too. Thanks for your time reading.

Do you need a slim line fan? Or are you just replacing the stock fan?

 

Replacing the stock, but a slim fan would allow my intake to sit much nicer, and in the future, if I ever decide to upgrade to a bigger turbo, I have the room.
