I don't think that is a good idea. What we need back there is a
way to adjust the down thrust angle. Figure out a good way to use
these left and right hand thread rubber rod ends. These are
perfect for the rear motor mount. The 1/2 inch size is about
right. Maybe welding some clips on the stock steel pan.

Why not capture a purpose-built fitting using the oil pan bolts like
the Schertz beam does on the opposite end?  It should be a simple
job to bend up some mild steel in a kind of "L" bracket.  Make a
similar bracket for the firewall.  Heck, you might even be able to
buy one or both of those brackets.

Then add:
  1 neoprene-isolated, female right-hand threaded shank rod end
  1 neoprene-isolated, female left-hand threaded shank rod end
  1 right-hand thread 1/2"-20 jam nut (maybe use nylon insert nut?)
  1 left-hand thread 1/2"-20 jam nut (maybe use nylon insert nut?)
  1 length of 1/2" mild steel unthreaded rod

McMaster-Carr web page to rod ends:

McMaster-Carr also has the right-hand and left-hand 1/2"-20 jam nuts
and the blank rod.  I'll let you look for them.

Cut the steel rod to approximately the correct length.  Using
right-hand and left-hand 1/2"-20 dies, cut threads on the rod (about
2 inches' worth).  Assemble rod ends, jam nuts, rod, and brackets.
Loosen jam nuts and turn rod with Visegrips to adjust (don't forget
to re-tighten jam nuts).

Hi Russell,

That's pretty much the way I built mine, but you only need one jam nut.
If one end can't turn, the other one can't either.  I also drilled out a
nut and welded it to the center of the rod.  That lets me turn the rod
with a wrench.
