    Sunroof Gaskets

    I am about to get into this project on my car and wondering about all the pieces.
    If i understand correct I need two pieces, the short one 990mm (54121870086) and the long one 1440mm (54121933203).
    But what about the single one 2370mm (54121972055)? is it actually too short?
    ECS Tuning lists them all for sale and available in 2 days. single piece would be cheapest at $80. the two piece option would be $114 (44+70)
    car is 1985 US model
    Thanks!

    I replaced the seals maybe 10 years ago? Used the 2 piece configuration and had to trim a bit to get a nice fit. The one piece unit does come in a bit short, so I would recommend the 2 piece for a certain fit.

    Thanks, that what I ordered. Any tricks to this or just pull off the old and put in the new? Any adhesive?

    Like you said just pull the old one off and clean the edge of the panel. I used a qtip to get a bit of silicone down in the crease of the gasket prior to install. It's a snug fit, so no adhesive required.
