Patrickt: Perhaps I took Detroit Bill's comment differently than you did.
Cashburn posted '9"
', with the 'smiley' indicating 'sarcasm'. I took that as his questioning why someone would have a 9" Ford rear end in their car, especially when he has a Backdraft with an IRS.
My perspective on Detroit Bill's comment was he was merely challenging Cashburn to do more than take a 'cheap shot' and explain his concerns or issues with a 9" live axle. Perhaps, as a purchaser of a car with an IRS, he'd like an informed opinion from someone who has one.
Just my $0.02.
