Shifter Hole Template for 4-speed for 1968
Short answer: A member produced an actual-size template for the 1968 4-speed shifter hole (for a column-to-floor conversion). Print it at actual size and follow the notes below.
- Remove the seam sealer along the top of the tunnel (under the dash) — that sheet-metal edge is the reference for all “Y” coordinates. A second reference line aligns with a rolled crease in the tunnel; check both lines agree before trusting them.
- Draw a centerline down the middle of the tunnel for all “X” coordinates (mark the center in ~10 spots and connect them — the soft tunnel radius makes this tricky).
- The hole is offset to the left, not centered — the shifter mounts on the side of the transmission.
- GM cut the factory hole very sloppily (looks torch-cut); to mimic it, cut ~3/16″ smaller all around and melt the edges randomly with a torch.
- After cutting, use the boot bezel itself — not the template — to locate the bezel/boot screw holes.
