Parts and info needed please...

[TnNinFLA]

We have an '86 Winnebago RV with a 2.2 gas Renault drive line. Apparently, there was transimission fluid put in the final drive unit hence it has seized up. We have been unable to free the CV axles from the trans. We are going to need the internal parts for the "final drive unit" and also any helpful hints on how to seperate the axles. ANY info would be greatly appreciated!
