Think of the game Battleship

Don,

The method I described would be stand alone. Layed up off the vehicle.
Lay out a 1" grid on 2 posterboards then locate the centerlines in both axis's and highlight them. From the centerline dividing the width, assign the letter A to the first line right of the centerline. Assign the letter B to the next, C to the following line (continuing working to the right) D to the next and so on until you've ran out of lines.
Moving back to the centerline assign letters to all the lines to the right of the centerline using lower case letters ie. a,b,c,d, etc.
Repeat the process for assigning lines for both fore and aft of the centerline for the length poster board. However use numerals for designators such as 1,2,3, on the lines fore of the centerline and -1,-2,-3 aft of the centerline.
Do this to both boards.

Youll pull your dimensional measurements from the cut out in the floor pan for TOTAL length divide it in half, and transfer these to both posterboards locating out from the centerline both fore and aft, draw a line across the width of the sheet at 90 degrees to the length centerline at both fore and aft locations. Lets say these lines intersected at 18 (fore) and -18aft (for a TOTAL length of 36".
Now measure the widest measurement at the cut out on the firewall for the bellhousing and it was 24" divide it in half (12") and transfer this measurement on both sides of the width centerline on FORE line 18. You should now have indicators on 18L and 18l Now take the width measurement at the aft position 10" again divide by half 5" and locate on Aft line -18at the E and again at e positions.
Lay a tape measure/yardstick along the cut out on the floorpan and working from the bellhousing back transfer the contour of the cut out onto the grid using the steps above. You don't have to indicate every inch, just where the contour changes.
Once you've completed this, you can connect the dots and you have a accurate but rough outline of the Topview of the tunnel.
Refine by eyeballing curves and contours and adjusting on the grid.

Repeat the process on the second board using the highest point of the bellhousing for total height and locate points of contour on the A,B,C / a,b,c, gridlines.
Label this side view.

Now that you have both layout patterns you can obtain the needed amount of EP for the plug.
If you are making your plug up from several pieces you can use Carpet Tape to affix the pieces together to form a rectangular block.
Once you have the block, draw centerlines in both axis's on all sides using a sharpie.
Cut out your patterns and trace the outlines on to the blocks aligning the centerlines from the patterns to the centerlines of the block.
Cut the sideview outline on the block first, making sure you remark the centerline back on the block after cutting.

Now cut out the Top view sections off the block and again replacing the centerlines after cutting.

Using your patterns you can now shape to finish form.

Clear as mud huh?

I've got to crash, I'll follow up tomorrow with diagrams that might pull this all together.
