Outer Limits 4x4 Board

Hi all,
My Dad is wanting to put an auto in his 1HZ powered 75 series troopy.
We were thinking the auto from a 1HDT powered 80 series would be the best bet as its a full hydrulic box, no electrics to worry about.

Has anyone done this swap. Will the extra length of the auto box cause ant drama's other than modifiying crossmember? Will the 75 series t-case bolt up to the auto.

Thanks
Steve

new crossmenber and longer front with a shorter rear tailshaft and i used a 60 series shifter
