I drilled out a clearance hole in the right frame rail. There are no suspension parts mounted forward of this hole; the only heavy thing forward is the right-side engine mount.
The little Automatic transmission support bracket that is spot welded into the tunnel had to come off. It interferes with the manual transmission shift brace (two rods go from the shift to the transmission, one is a brace, one transfers motion.)
Here are the spare parts:
And...
Here it is, stuck in the hole. Everything indexes off of the rear mount because the other mounts change. When comparing a manual-transmission-car's left side mount to an auto-transmission-car's the mount is 50mm further rearward in the manual car. So I'm engineering that up. And the right side engine mount will be totally different... the only point that remains constant is the rear mount.
