65 Barracuda w/500ci RB, Stage VI Max Wedge Port Heads, 6-speed, and 5.38 Dana
Prior to removing all of the 4-speed stuff, I took a measurement of angle of the engine so I could duplicate that angle when I install the T56 and start fabricating a mount. By measuring on the top of the intake, I came up with 3 degrees nose up.
I lowered down the back of the engine, so it almost sits on the centerlink, so I could barely get the bellhousing on so I could mark the floor to determine approximately how much floor I wanted to cut. I cut the center of the hump all the way to 3" above the firewall to floor seam. My plan is to spread the floor to enable installation of the T56, but we'll see how that works out later when I attempt to install the transmission.
I cut the floor on each side of the crossmember, cut out the spot welds attaching the floor to the crossmember using a spot weld cutter, and then pulled the floor back to access the spacers in the crossmember. On a side note, I can't believe how long I went without buying spot weld cutters; those things are amazing. I then cut the welds holding the spacers in the crossmember and removed them. I'll trim them later for use in the crossmember I fabricate.
Next up, cutting the crossmember just outside of the inner bolt holes. I forgot to mention, I unloaded the torsion bars a few days ago, so I could cut the crossmember whenever ready.
