Big block duster pain in the A$$

Well the problem being the studs on his conversion mounts don’t allow for much of a shim. I Was looking and i have have of the solution. I installed the original idler arm and that made a huge difference. I got an extra half turn. I ordered a new one, a moog and it's way thicker than the stock one. My car only had 20.000 miles so i am confident in this idler arm. Will only have to massage the pan a bit to get the rest.
