This is excellent. I would love to have an O/D trans but fear making the torsion bar support too weak. With your large press, you should take orders for the properly bent steel for the upper part of the cross member (You should sell a kit to people like me). Thanks for posting, this is great.
If you have subframe connectors there is an easy fix for this concern. Just triangulate the torsion bar crossmember into the subframe connectors.
