The fronts don't need any specs.. You just need to order the right length. OEM Banshee is 14.5".
Fox does not build Podiums for extended swingarms. They don't know shit about that kind of stuff.
You will need to e-mail Mike at ATV Galaxy. info@atvgalaxy.com
Tell him you talked to Tyler at BansheeHQ and that you need a Podium for your bike.
He will want swingarm length and rider weight..Since it's not exactly stock, you need to get a weight of the entire bike and add your weight, so he can figure out what valving and spring you need. Then he will send the specs to Fox.
