Yea I see what you're doing, trying to get it from the bottom too. Once you get that end on, should work good.Well, I went ahead and made the tool. I had a long handled 1/2" closed end distributor wrench that fit nothing I own. Pontiacs use 9/16". I can get way up there and just grab the bolt head from below, then tighten the nut with a long 1/2" socket on an extension from below. I'm still adjusting for the best angle but grabbing the head of the bolt is EZPZ now. I also make sure to only use stainless steel nuts and bolts on stuff like this with lots of anti-seize. I should have done this long ago!!
