I'm trying to fab my own trans crossmember to avoid me having to flip the stock crossmember around as is shown here:
What I'm trying to do is reverse engineer the stock engine mount and then redesign the mount with the appropriate offset to utilize all bolt holes as well as bolt into the transmission. The best directions I can give u are to imagine that u have a blank piece of metal and a chunk of rubber and u have to drill all the appropriate holes in the metal and cut the rubber down to the right size. A hand drawn sketch will suffice.
For anybody who needs it (maybe to help develop thoughts for other projects), I've written up a quick process to get the appropriate information [see below].
====================================================================
For clarity, we'll define some axes:
X-axis: An axis running along the length of the car from front to rear, the same direction the car accelerates and brakes
Y-axis: An axis running along the width of the car from left to right (passenger side to driver's side).
Z-axis: A vertical axis running from the top of the car to the bottom.
Note: For all holes, try measure to the center of the hole.
Pick a datum/reference point (most convenient in this case is probably the center of a bolt hole), and measure the distances to the other 3 holes in the X & Y directions. In the z direction, measure the distance between the two mounting surfaces of the chassis (i.e. the two surfaces the crossmember mounts to). U might be able to eyeball these, a straight edge might help accuracy/ precision.
Using your already selected datum, use a similar procedure and measure to the bolts that attach the rubber inserts to the transmission itself. Ensure you include dimensions for all 3 axes where required.

Argh... guess I'll stick w/ the plan...
