700R4 and e-brake cables?

[kpw 72]

I've been searching high and low for awhile now, but can't seem to turn up an answer:

When swapping from a 350TH (automatic) in a '72 LWB pickup, the crossmember has to be moved back a two-three of inches. Does moving the crossmember back interfere with the parking brake/emergency brake cables?

Everyone mentions driveshaft, etc... But is there anything else:
parking brake, brake lines, speedo cable, etc...

Thanks to all!
