I guess with the 88s, the bolts are pricey especially the long bolt.
Last I heard they were still available at GM but @ 22$USD for 1, I suppose that scares people.
It would be a nice project if they matched the original and size (18mm size wrench). As I like to keep my 88GT original, I would
guess that would be the right option.
As long as they are 10.9 metric grade, would be nice to your dedicated 88 web- page for parts.
