Over thr rail on the door? What kind of jeep do you have, I own a TJ.
There are button snaps over the tailgate, velcro over the middle seat kinda, than plastic belt things over the doors, and than the clips on the windshield. Thats how my top is setup. If you need something lemme know, pretty sure Im just buying all new top instead of repairing mine.
God I used to hate those snaps...such a pain in the arse, especially once you see how simple the TJ tops are.
Back on topic though: My old YJ only had about 6 snaps total. I just kind of rationed them between the drivers and passengers side and spread them out as evenly as I could. I looked and never did find any. The dealer told me I had to order a whole top so I just decided it was fine how it was.
Sorry I'm not able to help solve your problem.
