The piston will come with some mounting hardware including a clevis that screws onto the end of the threaded piston shaft. That allows you to mount the "moving" end of your piston with either a pin/bolt/bailing wire/etc. as a pivot. The body of the piston can be mounted in a couple ways. The piston will come with brackets to mount the piston using the pin on the end of the body. The pin at the end of the body (only on the 3/4" and 1.5" bore pistons, I believe the 2" bore has bushings) can be pressed out and a bolt can be used in it's place. There are also threads on the body of the piston to allow for mounting of the body of the piston without a pivot.

There might be a couple things I've missed, I'm sure others will chime in.

As a side note, look to protect the smaller bore pistons while in the extended position to prevent irreparable damage during competition. (These things bend very easily when whacked into hard objects.)
