I annealed the pipe and bent it up to suit, it was a bugger of a job. i have the 2 coolers, one in the original position and one above , I had to move my horns, by the way this is on a 89 Rangie. there is not much room when the coolers re in so I basically had to connect them with the coolers towards the front and then push them back and bolt up. its very difficult to get a spanner behind as the aircon condensor and fans are in the way.
A disco may be easier.
Overall I am very happy ..sorry no pics

parallel is better if using two. Slower oil flow promoting better heat transfer when oil passes thru the coolers, but As you say, fittings may be the issue. A good transmission place should be able to sort this however particularly someone that specializes in autos.
