I recently purchased a cover for an 8.8 Ford rear from the US and had shipped to CA and then downunder. I went to install it the other day and then found out that it does not fit my 8.8. I placed a new gasket on it to show the difference in bolt patterns and as you can see they are vastly different. Damn expensive exercise for nothing more than a paperweight. It requires significant rework to come even close to fitting. What differences are there in 8.8 rears?
