auto cross member help

[67cst]

hey guys i have a question for ya...well 2 or 3 maybe :p i used an 85 auto cross memeber for the th400 on the shortened 71 frame, what my question is will my hump in the 67 cab clear the tranny? my dad bolted up the lokar shifter to the tranny and he thinks the tranny might rub against the bottom of the hump...we are going to put the cab on this weekend to see forsure but could someone tell me if it will or not, and if it doesnt hit how much space minimum should there be in between the tranny and floor, and also if they hit we thought about putting i high hump in the floor instead of the stock low hump, which leads to another question....do any humps un bolt or are they all part of the floor? thanks a lot for any help guys
