Can you tell us about the front differential you are having put in?
Everyone I talk to lazily says that anything strong is too big to
fit...
Im sure there is a solution.... Did you have one?

Sounds like option 1 is the route to go...great response much
appreciated...despite all the stupid posts recently the SYTY list
comes
through again...Thanks to everyone who responded and I hope to see
all of
you in KC....Ryan
