Gas struts for 93 Jayco designer

Yep, + 1 To that, a Jayco agent will advise you the correct strut to replace with. Other option is to remove it & take it to some place that sells them & see what they advise.

We had a faulty one on our Jayco Pop Top a while back & we purchased replacement units from a caravan repairer as it was cheaper, He advised that we should not mix new with old as it was important that all four struts be able to apply equal pressure, so rather than just replace the crook one, "bite the bullet" & replace all four. Seemed to me make sense so we did.

Good luck & safe travelling.
