The roof kinematics latch is broken. I see the part on Scuderia. Shipping from UK. Could be a few weeks. https://www.scuderiacarparts.com/part/236603/ferrari/82973500/lh-roof-kinematics-latch.html And I've found some other pics where we can better see how the plastic runs along the track. The hydraulic pistons push this and that latches the top. I also found a complete assembly on ebay https://www.ebay.com/itm/133653853382 Shipping from Sacramento. I am in LA. My mechanic wants to buy the eBay unit. He says there is a benefit of replacing the whole assembly VS trying to remove just the track/ kinematics latch. If there was an issue with the piston too. We'd have another piston. What do my fchat friends think? Used eBay. Shipping faster? OR oem new in maybe a few weeks.
