99 GTP radiator size?

Flushed mine because it had mud like slop in it, and as expected I have a leak on one side. I was checking replacements and I see there's a 5/8 and a 1 inch. I'm assuming the 1 inch is for the supercharged motor? I don't care about oversized ones, just want to put the lowest cost one in there.

gtp would use the 1 inch, but the 5/8 th's also works. i got a 5/8 in my regal gs, temps went up a little bit, but no where near hot.
 
Bought a 1 inch off eBay for 63.95. Local parts store wants more than twice that even with a discount code. I was concerned about getting one without a warranty, but with 200k miles on the ride, I'm sure this one will outlive the car.
