flex-converter hookup

IF I decide to go with this 4.2 to 4.0 swap, does anyone know if the 4.0 flexplate will bolt up to the existing torque converter? I'm fairly sure the tranny is a 727, but not 100%. I've put a new front seal in it but can't recall. Any leads would be helpful at this point.
Also... were the TJs the only Jeeps that used the 4.0?

'85 CJ-7, bone stock exc. 2" shackles & Skyjackers. Engine is 258 (for now). Nutter bypass.
