These come 6 to a package, so you have two spares. All mounting hardware provided. Only 16 bucks.
I chose these because the longer ones didn't have enough travel to work in the space provided, and the total force matched the load better.
Ideal: Holds the pop-top up without need for lashing it to the mast in calm conditions. Otherwise, holds it in place while you lash it to the mast. No more two-person operation or fumbling with the lug slot clip, which was constantly fouling the jib sheets. If one fails, the others will still hold the top up.
Less than ideal: Because of mounting limitations, these don't provide lift assistance until the top is about halfway up. Past that, don't force it, because the action is damped and doing so could bend the mounting brackets. Ask me how I know.
See photos for mounting details.

These look nice, and don't get in the way.

Use these measurements when mounting the brackets

Add an extra screw to prevent the brackets from slipping out of place
