Thanks to the list for much information.

I'm helping a new owner with his Lancair 360.
His canopy lift struts are weak and I'm not sure which model should replace it.

The present ones are 21 inch long extended but are
17 & 1/4 installed.   I found a similar one at the auto parts store but its way too strong.
What pound rating works best?

Thanks
