Hydraulic Clutch Master Mounting Location

we had a McLeod hydro T/O on an 833 in a 340 65 A. We had to run a trans support bracket from the clutch M/C bolt to the inner fender so the firewall would not flex. We had terrible 'feel' without that bracket and the flexing. And bleeding the line to the T/O was a PITA as the bleeder was on top of the hose.
