67 Dart 270...Project Old School
I built my transmission cross member out of 1/2" mild steel tubing and some 1/8" x 1/2" mild steel flat bought from Lowe's. For the actual mount location I used some rectangular tubing I cut out of the main support of a Harbor freight engine stand to shorten it so it would fit under the work bench with a short block attached.
Here is the tubing:
Here you can see the flat steel welded in place:
This makes for a very stiff unit.
Here is a shot showing the tube welded on the end and bolted to the torsion bar frame:
I took the rectangular tubing piece and cut out one long side to get a U shape with the long side on the bottom of the U. I then bent down the two short sides to get the angle I needed to meet with the tubing arms. I drilled the two holes and bolted this to the rubber mount already bolted to the transmission. I actually made the two side arms and hung them then swung them around to meet the plate and tacked it in place while under the car. I unbolted it all and welded it on the bench.
This is a dark picture of the center mount portion bolted to the transmission:
So far the cross member has survived 10 passes at the track and about 400 road miles.
