i believe so.. i cant find mine under car.. and last time i looked, i never saw a trap door anywhere, but not sure where it should be..
thats why i wonder if you and your vast knowledge base did it yet lol
Made my own gaskets with this and black RTV 16" x 72" Solid Chest Tool Drawer Liner at Menardsif you didnt get the gasket kit with it i recommend silicone around the bolt holes, i did it and no issue with leaking ever.
I have 3 bad ones and 1 that would pass as mediocre at best.Yeah the back 2 are absolutely horrible
