4 speed tranny and cross member question

[spookylynx]

this is all for my 65

So, I'm replacing the 3speed with s 4speed. No sweat. my question relates to a crossmember at the tail housing.

I know they both basically hang off the bell housing, but the 4spd is obviously a bit longer and gets mixed up in the ebrake linkage.

Ive read where some people have flipped the ebrake xmember and made a transmission mount and I have seen where others say that it is bad to have 3 mounting point in the engine/ tranny combo.

I guess what I'm asking is, is it bad to have mounts at the motor, bell housing, and tail shaft? or do I just let the 4spd hang off the bell housing with no other mounts.

I'll just be running a mildly built 350, not high HP.
