95 yj Rio Grande radiator swap question

New (but old) kid on the block. this forum seems similar to the Toughbook forum in format. I look forward to learning and hopefully sharing in some areas on this forum. Have some experience with Mustang 5.0 police versions and caprice police 9C1's with mechanical upgrades and just purchased a 95 YJ Rio Grande I4 auto with 129K on the clock. Went and did a dash removal to get to swapping in a working(lightwise) instrument gague(shorted out ribbon cable wiring harness) , a brembo front rotor replacement with ceramic pads and just got in a Champion 3 tube alum radiator I was hoping to install. That's when I encountered the problem of the auto trans oil cooler line hookup incompatibility. It has the new style quick detach coupling with the external added auxillary trans oil cooler as well as the bottom tank mounted oil cooler. The end of it fitted into the old rad with a 1/8" npt fitting and the new rad has the inverted flare 3/8" female end. Supplied with the rad was corresponding nipple connector that many would just probably just use trans rated rubber hose to clamp and hack together. That doesn't appeal to me and was wondering if you guys knew of an adapter that would mate with the inverse flare 3/8" end on the rad side and allow the use of the the stock trans oil cooler lines with the 1/8" npt thread end. If anyone has like a dorman number or item number or website or seller that has what I feel would be a more substantial fix here please enlighten these old ears..many thanks in advance........Driller
oh yes, I did hit the local parts dealers napa oreileys carquest advance auto and the like not the chrysler folks yet.

have had a really fun time trying to swap in a new radiator for this little rio grande. the radiator was a champion 3 row all aluminum and looked to be pretty much a straight bolt on with reconnecting the lines. that's when the fight started. the oil cooler lines that fitted to the stock radiator were 1/8 inch npt or pipe thread. the new radiator appeared to be a 3/8 inverse flare male end with the 1/8 female and the adapters ordered should have allowed for a smooth connection. that's when the fight started. the adapters have yet to arrive and I finally got up with someone at champion and he told me I had a M16 1.5X1/8 i.e. metric my friend not standard measurement. back to the drawing board and went back to eastern hydraulics to piece together 3 pieces to get the adapter to mate up to the oil cooler in the radiator. well now were making progress, right? the radiator bolts up close to original but is a couple of bolts off on the passenger side. will drill holes in fan cowl to allow tight fit. got the trans oil cooler line,I believe the pressure line hooked up and went to connect the return line when I noticed it was corroded to point of being split in two where the bracket keeps the 2 lines from touching each other. Now I believe the best thing to do is to look for two complete new trans oil cooler lines. this leads to my new thread that I'm about to start asking where is best place to get new trans oil cooler lines........fun in the flatlands........Driller
