Well, so much for going 4 wheelin yesterday.... broken driveshaft

[AlamoJim]

welding aluminum is tough enough - but that has
to be 2 different types of aluminum which would be even
tougher (as explained above)...what
possible purpose would you have for going this
(I assume) much more expensive route - that would become
a probable weak link in the drivetrain? I mean sure,
you would save some weight - but at what cost?
is it so you can shine it up and 'bring the bling'?
