How to increase the width for a specific radio button?

I have 3 radio buttons horizontal aligned and I need to increase the width only for the second one. (I have limited space in the line where I'm displaying the radio bttns)

Using :
#my_radio .aw-item-template {width: 80px;}
increases the space between all of them. How do I specify different space/width for each radio button?

Thanks!

<style>
#my_radio{ left: 100px; top: 120px; width: 300px; height: 18px; }
#my_radio .aw-item-template {width: 80px;}
</style>

var search_radio = new AW.UI.Radio;
search_radio.setId("my_radio");
search_radio.setItemText(["Sale", "Anonymous Buy", "Buy"]);
search_options_radio.setItemCount(3);
search_options_radio.setClass("flow", "horizontal");
document.write(search_radio);

search_radio.getItem(1).setStyle("width", "150px");

Alex,

Unfortunately line above didn't work. Seems that the method is not supported by the radio bttn. I got the following message :
"Object doesn't support this property or method"

Is there any other way to do it?
Thanks!

This code is for AW 2.5. If you are still working with AW 2.0 then use

search_radio.getItemTemplate(1).setStyle("width", "150px");

Thanks Alex!

I'm using 2.0 ... so the second solution worked perfect for me.
