I have a 92 bronco with a bench seat and was wondering if any one knows if bucket seats from a 90 bronco will bolt right up without any modifications.

 

pretty sure you can without drilling..should be no problem; see here for a pic of the seat mounts:

see the buckets' mounting holes?

thanks to mrlaserboy for the pics!

use grade 8 hardware too!

and check the classifieds; someone wanted a bench seat once and others were selling their buckets
