...I have to say it! Rene, YOU are Serious about 'Frame Stiffness'-Triangulation!! You did not say if you plan to 'Race', or all this bracing is for 'the Street'. My point being...did you keep track of the Weight of Steel you added to the Rear, Entirety, of your Pantera? Looks as if it could be over 200 pounds, perhaps, closer to 300*, added to the rear. IMO this does not 'Improve' very well, towards the cornering/handling response. NOT trying to piss anybody off...just bringing this to the equation.
* That's equivalent to having TWO People, Permanently laying in the Engine Bay!
Great Work, though!

P.S. ...Quote: Ferruccio Lamborghini..."Weight is the Enemy!". Although I HAVE added vendor sold cross-members, I am constantly 'weight-stripping' My Pantera. I have Her down to around 2700 Pounds or even less. Started 21 Years ago...exchanging the 20 Pound Cast-Iron Waterpump, for a 8 Pound Aluminum. Good-Luck getting Your Pantera back on the Road!! Your in for a Lot of Fun!
