Follow the R&R procedure in the Chevrolet Service Manual; that's the best advice I can give. The job will take quite awhile. Mitchell's Labor Estimating Guide gives a time of 2.8 hours for non C-60 and 4 hours for C-60 cars. However, this is for a professional mechanic. You can probably figure twice that time doing it for the first time as an amateur.
