The original 727 lines were 5/16" which is equivalent to AN5 but AN5 is an orphan size so AN6 is the preferred size, AN4 is too small.

I use AN male nipples 37 degree flare to pipe male fittings(different sizes, # 6 to #12 and in between) all the time, is this what your calling inverted flare? If so you will need the proper size nut, collar and flaring tool for the size you want to use  If you want to use AN stainless covered hose make sure and order teflon lined hose, not neopreme 
yes, inverted flare or 37 degree flare, ive always called it inverted flare. Where's a good place to get the teflon line hose at  ? Thanks!!

I buy some AN supplys from Summit and some from G&J Aircraft Surplus, 909-986-6534, in CA. G&J use to have (I haven't been to there store in quite a while, 15 YRS or so) a lot of surplus AN hoses in all sizes and lengths and linings They where very reasonably priced also Do you know if the pipe threads in the radiator and the outlet size on the cooler lines from the tranny are 1/8 pipe or 1/4 inch pipe thread? I think you can buy double male nipple reducers from 1/8 pipe to both #4 and #6 AN, if I remember correctly the trans outlet pressure to the radiator is under 20 lbs so pressure is not a issue, the tranny fluid temps are the reason for using Teflon line stainless hose

Im still using the stock radiator. 99 dakota, the cooler lines run to the radiator via 3/8 line. So i have to get inverted flare to an at the radiator. As far as the tranny, yes its 1/8 npt. I wish i could find some 3/8 inverted flare to -6 and 1/8 npt to -6, ill call that place tomarrow and do some hunting around. Thanks for the reply's!!!

All of the hydraulic fittings I have bought are steel, no aluminum unless you ask for it and then they have to order them
