Rear End

How difficult is it to replace a pinion and a crown back?

I have a mustang 1989 which has a 1987 turbo coupe thunderbird and the trans was swapped from auto to manual. The rear end gear ratio is 3:73 and I want to leave at 3:45 a. I good mechanical skills but I'm more of a shade tree mechanic. I was just wondering how difficult it was for you to replace the ring and pinion and do you have any advice? The back is a "7.5.

Pretty straight forward for a person capable Mechanical - book search (Haynes or Chilton manual) to get the correct torque, bearing clearances, etc., and a good set of feeler gauges and a wrench.
