The MacPherson strut is a type of car suspension system which uses the axis of a telescopic damper as the upper steering pivot. It is widely used in modern vehicles and named after Earle S. MacPherson, who developed the design.

No, a Macpherson is a strut -shock combo unit that fits between the A frame and the vehicle frame.
You can go to any local mechanic to get your MacPherson strut installed. The mom and pop shops are usually cheaper, but take a little longer than the name shops.
The same way you do any macpherson strut assembly...If you aren't familiar with the procedure, take it to a professional. Spring/strut assemblies can be dangerous if not serviced properly.
A strut is actually part of the suspension and not the engine. The strut is a shock absorber surrounded by a spring and provides the upper pivot point for the steering. I suggest doing a google search on "macpherson strut".
The strut consists of a damper and a spring (shock).
One lower control arm for each front strut.

Honda calls it a damper. If you want the front damper. Remove the brake hose clamps from the damper remove the damper pinch bolt (on the bottom). Remove the damper fork bolt. then remove the damper by removing the two 10 mm nuts on top. Do not try to Disassemble the Damper without a spring compressor.
Put front of car on stands or on lift. Remove wheels. Remove three or four (depending on model) strut/damper mount tower nuts (under hood). Remove strut/damper to spindle bolts. Remove damper/spring assembly and replace with new. You may replace it as a complete assembly or damper only. If you plan on replacing the damper only, you'll be required to remove spring from old damper and transplant it on to the new Cheers
