Rocketman: removing and then modifying and then reinstalling that crossmember is certainly doable, however, I’ve attached photos of how I addressed that roadblock. I cut out the center of that crossmember and then fabricated a removable tie-plate of 1/8” steel to straddle that opening. Those are 1/2 inch grade 5 bolts (4 on each side) bolted into 1/2” coupler nuts bolted onto the flange at the bottom of that crossmember. That flange is plenty wide to accommodate the bolts. You can then also adjust the position of the tie-plate as needed to get clearance for the transmission oil pan. Good Luck, Dave
