Are the FCP Groton bushings (rear suspension 89 Volvo 245) of sufficient quality to be considered as replacements? Whole set of ten is or so. [Rubber, not urethane.] I'd hate to do all the work of installing them and then have someone tell me to use better replacement parts. They have the best pictures and descriptions of the parts, but do they have a quality part's replacement?
