71 gas gauge

[justbuggin]

We're new to all this ... just brought a 71 beetle and started work on it. Runs good ... needed new floor pans ... but it's roadworthy EXCEPT the gas gauge doesn't work. There's juice to one end of the gauge and at the gas tank. It's imbedded in the speedometer and I'm looking for some direction on where to fuind another one and whether the whole speedometer aasembly needs to be replaced. Any help would be appreciated. Thanks
