t-56 70 nova. Tranny tunnel question

[LowchevyII]

Might be a dumb question but hey, Ill ask it anyway because this inquiring mind is getting very serious about dropping a t-56 in.

Anyway, i have a 70 nova with a th-350 and a small block chevy. Im working on a lq9 and t-56 swap. When i put the tranny in, does the tunnel have to be modified. Ive seen a few modified and my lack of fab skills puts this almost out of reach. Is it a true necessity to mod the tunnel to get this to fit?

thanks guys
