    While researching replacement kits for the hydraulic lines for the convertible top, I've found three sources. Wondering if anyone has had any experience with any of these, or if there's another option I'm not seeing.

    1) https://tophydraulics.com/ferrari-355-f355-spider/330-f355-full-set-lines-pipes.html

    2) https://www.ebay.com/itm/132668913895?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&mkscid=101&itemid=132668913895&targetid=2315428264780&device=c&mktype=pla&googleloc=9051857&poi=&campaignid=21399024886&mkgroupid=173029507188&rlsatarget=pla-2315428264780&abcId=9447167&merchantid=6296724&gad_source=1&gad_campaignid=21399024886&gbraid=0AAAAAD_QDh_NwZloSFZkSMhriFQJiHJqr&gclid=CjwKCAjwi4PHBhA-EiwAnjTHuZJdB-sdNILQ1_m3GgojLF42rNPsrUVeldOn78FCSrRz5U65A9V68RoC9lEQAvD_BwE

    The ebay kit has the highest burst rating and is a little less expensive than the first one.

    The last one has a much lower burst pressure rating, but it's still above the working pressure with a decent safety factor. It's also about 1/2 the price. I'm not sure what they mean when they say: "These hoses use different fittings to secure the hydraulic pump and cylinders."

    Looking for comments/feedback and any info offered. Thanks!

    I was considering that, but since everything still seems to work, changing the lines out is worth it IMO. I just fixed the passenger seat POT and had them calibrated. The fluid level is low so there must me a small leak somewhere, and I know the interior of the lines degrade over time. Keeping everything working properly in the car is what I prefer, if possible.
