I purchased on ebay for about $30 and installed. It took longer than expected. The clips were somewhat difficult to get on towards the bottong of the strut. If you use a towel in case clip falls off and have someone else help, you should be able to do it in less than 30 minutes. The struts were identical to the originals which I removed from the car. Good luck
I purchased mine from ebay for $50. Installed during the roof opening, stopped the sequence 1/2 way. this allowed easy access to both top and bottom of assembly.
