I'm putting a O500 trans in my swinger. I'm using this trans cooler and was wondering if it mattered what direction i have the in and out nipples???

Any way is fine, whichever gives you the neatest hose routing

Wash it out good with carb cleaner & air but make sure it has a real 3/8" hose barb that matches the size of your lines or your OD unit will starve/heat up
If you are wanting to use your stock radiator, you can't for this very reason
The first thing Chrysler learned about the OD transmissions was cooling & line size effects on the OD unit itself

What Bob said made me think & the OE lines are 5/16" OD & some aftermarket coolers are 3/8 & that pair of brass fittings (npt/inverted flare) that screw into the trans case are available in the next larger size (3/8") so if the passages inside the trans for the fluid going in/out to be cooled are larger than the ID of the OE 5/16" line then I'd think there'd be a bennie to going to the next larger size of line/fittings for more flow 
. EDIT You would want to drill/npt tap the case while the trans is apart/case is bare

The A500 from 91 up should already be setup for 3/8" from the factory I know the A518s are

just watch that the case "nub" has enough meat around it for the oversize drill/tap, because if it doesn't, it will crack because the threads are sure stress rizors. then it's new case time if you can't weld up/remachine the crack. not all cases have enough meat to do this mod.
