99 Accord – Snapped stabilizer bar bushing mount screw

Hey Guys!

I was replacing the bushings on my stabilizer mount and one of the rear screws for the bushing mount snapped and is stuck in the subframe and nut on top. I’ve tried accessing the upper nut with wrenches but the exhaust is in the way. I’m assuming I’m going to have to drill this out, so does anyone by chance have the specs like the thread pitch for these bolts and nuts? I’ve looked in a service manual I have but it doesn’t mention the process of removing or replacing the stabilizer bar or the end links, just that you have to remove them to access other parts.
