If I remember right it took a little finesse and I had to install the bracket on the block the bracket on the frame and then I think the polyurethane was last as we bolted the clamshell together. Minus my helper up top taking a chip out of the firewall paint for not paying attention while I was under guiding the tranny in. It went well.
Don't forget to fill the converter first and I opted for an SFI approved flexplate just to be safe.
Good luck
