i just bought the back seats for my crx but they didnt send me any bolts for the seat belts or brackets dose anyone know if the bolts outa any ef will work or from anything else eg,da,ek etc. any info would help thanks

 

i cannot speak for the belts, you likely wont even have belt mounts on your car because it never came with rear seats, but i know the mount brackets for the seat back are a standard bolt that is the same as almost every bolt on a civic/crx (10mm)

 

Well, it's not exactly a straight bolt-in procedure, you'll have to a little extra...check these threads out:
