Passing URL parameter to iFrame

I have a page with a part store that is being displayed as an iframe. I’m using a plugin called Advanced iFrame Pro, and I want to pass a parameter to the iFrame to allow me to display parts for specific models.

This is the URL being used:
http://partstore.agriculture.newholland.com/us/AlmaTractorEquipmentInc/parts-search.html#epc::model_find

The ‘model_find’ can be replaced with a parameter to display the results for a particular model.

Example:
http://partstore.agriculture.newholland.com/us/AlmaTractorEquipmentInc/parts-search.html#epc::mr52330

My goal is to make references on my site for popular models, and take the user to that exact page. This will also help me out with SEO, having some of the models on our site directly.

Can someone help me out with this? I need an easy way to attach a parameter to a link. Then pass that parameter to the iframe. I’m trying to avoid using iframe on a bunch of different pages, and have a modular page.

Thanks in advance!
