So i bought the steathmode oil like kit and it comes with the straight brass fittings. I already got the oil pan welded with the straight, and i was wondering where online (i've had no luck at local auto/hardwear stores) can i get a 45 degree brass fitting on the turbo side.

Its a 3/4inch threaded side that goes to a 1/2 barbed.

Any help would be great
