i read the thread about the neon radiator, but he is unsure on two things and i just wanted some clarification before i make any mistakes.

1) What year neon radiator is the half radiator?
2) Where do i find a filler neck and for what application would i use?

 

"Turns out the 95-99 Neon non-A/C rad is virtually the same size and thickness as the stock EG rad but its not as tall thus making this a perfect candidate. It will have to be mounted upside down to make best use of the coolant necks. Note: If you are building a track car you might want to consider a bigger radiator. A spal 1250cfm fan was also purchased, it fits the neon rad perfectly."
