Hi Trebor,
nice vid, seems you had a lot of fun that day. With the axles it´s the same problem here in germany, very expensive stuff - and then you still have to rebuild it.....
I´m looking for a Ford 8.8 out of an explorer to put it into my valiant. Reasonably priced, strong, good gear selection and most have sure grip. You have to modify this one a little bit but i think it´s worth the effort for us. Do a search here for ford 8.8 or 8.8 axle swap then you will get a lot of information.
best regards
Michael
