Yes, you'd need an alignment following strut replacement.

I've had a couple of hi mileage H body GM cars. The suspension parts (aftermarket) we're big $$$, IMO. Are you doing the work on this car or farming it out? I'd service the transmission if it hasn't been done.

When these old GM cars are running right and in decent condition, they're as close to driving for "free" as any car could ever be. I got rid of my recent car this past summer. It had 175k on it and the 3.8L and trans worked flawlessly. However, being a resident of the Northeast its entire life, rust was becoming an issue in some areas I'd consider safety related. Cosemetically, the car still looked great (as long as you didn't approach closer than 10' )
