Loctite Hysol 11C glue is actually a really good 2-part epoxy.  I use it to repair lots of things.  I keep it inside, but the shelf life has been pretty good, lasting over 2-decades.  Used it last December and it was still good.
 
	That Dorman kit worked pretty well for me, I think I repaired at least 2 W-bodies with it and never had a repeat repair.  Shame it's not sold any more.  It was supposed to be equivalent to OEM replacement ends and looked identical, so you didn't need the Moog blocks with them.
