On the T1 Silverado 1500 the front "strut" is really a coil-over shock absorber bolted between a frame bracket at the top and the lower control arm at the bottom. That is good news: the wheel bearing, knuckle, tie rod and camber settings all stay put, so swapping complete assemblies is mostly a matter of two mounting points per side and does not automatically require an alignment. The job is the same across 2.7 turbo, 5.3 L84, 6.2 L87 and 3.0 Duramax trucks because the engine has nothing to do with the front damper.
What varies is the suspension package, not the engine. Base 2WD, Z71, Max Trailering and Trail Boss (which is factory-lifted about 2 inches) all use different part numbers, and a Trail Boss fitted with standard parts will sit low and ride badly. The one thing people get wrong: pulling the lower through-bolt with the control arm hanging in full droop. Jack the control arm up to roughly ride height first, and both removal and reinstallation of that bolt go from a fight to a two-minute job.

Fastener sizes do not change with the 2.7 turbo, 5.3 L84, 6.2 L87 or 3.0 Duramax; the front suspension hardware is common across the T1 1500 line. What changes is the part: 2WD, 4WD, Z71, Max Trailering and the factory-lifted Trail Boss each use different shock assemblies and spring rates. Diesel-equipped trucks carry more front weight and may use a heavier front spring, so order by VIN.

Usually not, because this is a coil-over shock, not a MacPherson strut, so it does not carry camber or caster adjustment. Still, have the alignment checked if ride height changes noticeably or the steering wheel is off-center afterwards.
Typically 18 mm on the upper mount fasteners and 21 mm on the lower control arm through-bolt and nut, with 22 mm lug nuts. Check yours with a wrench first, since some trucks have had hardware replaced.
Yes if you buy a bare shock and a proper coil spring compressor, but on the T1 most DIYers install a complete loaded assembly. Compressing a truck coil spring is genuinely dangerous without the right tool.
It is usually rusted into the control arm sleeve, and the arm hanging in droop puts side load on it. Support the control arm at ride height, soak the bolt in penetrant, then drive it out with a brass drift and dead blow hammer.
