Can't get bottom bolt on a 79 rx7 caliper...help!!!
 

:dunno:

Have you tried the WD40 and letting it soak? I usually wrap a towel around and spray it and let it soak into it from the towel and wait an hour or 2 and try it again

this bottom bolt that u can't get, is it the one that u have to unbolt the lower ball joint form the bottom of the spindle to remove?

Which bolt, the caliper to bracket bolt or the lower bracket mounting bolt?

You can't remove the bolt or you can't find a replacement one? Inquiring minds want to know.....
