This is a decent unit, but there's definitely a few issues. The overflow doesn't line up quite right and it could be much tighter. I understand bolting it in, but that does make it more challenging to remove so adapting it to come out a little faster would be nice.
This will help if you're looking for a bit more space, especially if you have the Mishimoto radiator. We're gonna take it apart and modify the mounting a bit, but it works and is pretty decent starting place if you're not looking to completely re-work the whole radiator shroud.
