How to repair a 62 Fuel sending unit in my lancer

Hey guys,

I have a 67 unit, but its got a different float arm and pickup, as well as range for the float. I wasn't sure if I could adapt it or not. Anyone have some ideas? There are pictures at: http://menko.no-ip.com/files/lancer/su/

Please email me with pictures if you have one or know of a place I can get one. OR post here if you can help me modify the 67

Thanks!

MJ
