Pretty straight forward but here are some photos if anyone is thinking about doing it.
Front
I bought new shocks for the Pontiac. The old ones were are not in bad shape but they are old (late 70s) so worth replacing.
The job is super easy in theory. Unbolt the top bolt and two at the bottom. Slide shock out, slide new one in and re-bolt up. The top of the shock mount on the driver's side. Nut is 9/16" but the middle needs to be held in place. A 1/4" wrench works. The driver's side on came 98% of the way out before seizing solid. Likely some bad threads at the top.
Some work with the angle grinder and its off.
Bottom of shock mount - two 1/2" bolts and the shock slides out.
New one bolts in without too much trouble.
Passenger side went super smooth thankfully with no seized bolts.
The fronts are done. Now onto the rears.
Rear
Old shocks - I have the receipt for their installation in 1977.
Shock bottom mount - Axle needs to be lifted a little to get shock off. 3/4" bolt size.
Top mount has two bolts with nuts. 1/2" in size. I sat a 1/2" wrench on top and 1/2" socket turned from underneath.
1/2" bolt on the top mount. Not visible from below.
Shock out
Rear shocks - old vs new
New shocks installed - nice and straightforward - took 1/2 hour.
Next up is brakes.

Good straight-forward tutorial and done old school ... on the ground, cardboard on concrete.

Dang....I wonder if they are the originals, or maybe a set of factory or NOS shocks replaced later in life. I can't imagine they'd be originals after 57 years...
