Which radiator do I have?

Here is scoop, I have an '88 MJ I just bought.
It has a transplanted 4.0 in it.. the radiator need replaced.
I don't know what year to tell the parts store.

It's an open system, w/ rad. cap on the drivers side.
The upper hose is on the passenger side top corner, the lower hose is on the drivers side about 2/3 way down.
There is one tranny line connector on the drivers side, just below the rad cap stem.
It sits on two pegs that slip into holes in the front cross member.
Anyknow know what year this would be from?

'89 - different
'92 - different
'94 - different
All different radiators used....
I'm not sure if my 4.0 is a High Output of not? How do I tell?

All those connections you described are exactly what my '94 radiator is like. I don't use the tranny connection though cuz mine is a 5-spd, so I didn't pay attention to where that connection is.

Dunno if that would help you any, good luck with it.
