General Maintenance & Repairs - Question about LT1 Radiator Conversion

Can anybody show me an LT1 style radiator next to an LS1 version? I am confused. I know there's a heater outlet line on the lower drivers side that needs to be plugged if I get the LT1 radiator, but what happens to my factory 1999 coolant level sensor on the upper drivers side of my LS1 radiator? I don't want to ghetto the install, so if an LT1 radiator doesn't have a provision for the coolant level sensor in the same spot I'll just get the LS1. LS6427 (I believe that's his user name) has been helpful but I am ordering the radiator online and I don't want any surprises when it gets here. Thanks.

This is the LT1 radiator, the temp sensor goes in the same place. See how the other tube is capped off. The radiators are IDENTICAL, except for the other tube that gets capped off and the LT1 has a 30% larger cooling capacity.
Buy it and put it in, you'll be happy.
