Discussion and technical advice the SW20 MR2. 3S-GTE, 3S-GE, 3S-FE etc
Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
NO
The quarter window is bolted in. There is a bolt behind the vent grill and some on the inside behind the plastic trim. It is also sealed in with some butyl type stuff.
If you search on here for quarter window sealing you may find the toyota number or a link to the 3M stuff people have used.
As above the window is bolted in although the metal tabs with the studs on are bonded to the glass.
So although they could be coming loose the window should still be stuck on pretty well with the butyl strip/gunk.
