IMO, I think that's your best solution. Otherwise, you've got a lot of work ahead of you. Be careful which radiator you go with if you do that. A lot of them out there are not made well. The cores are positioned badly and end up being to far "back" into the engine compartment with a big gap between the core and the radiator support. That ain't good. A lot of them are like that, too and it's tough to find one that's not, because of the mass production make them all a little different and made to the "WRONG" specs, so be careful what you buy. I would try to look for something like an original three row factory radiator. The fit will be much better and I think you'll get the room you're looking for.
