drive train change/ crossover question

[Jjay78]

i am switching my 350/203 out for a 700/208, and i got teh taller adaptor plate with teh 700/208 will i ba able to use the flat cross member from teh 350/203 or will i have to get teh "wavy" cross member for the 700/208?, asking because i don't really wana lift everything up into place 2x, and i figured there's gotta be a few people that have already made teh swap
