We use banjo fittings on our oil cooler kit, but for cars with front mounts we recommend a forged 90 degree female/female fitting... It brings the thermostat back slightly for more clearance. We were also concerned with the weight of the thermostat and lines causing the fittings to come loose over time, so we made a mount/brace to hold the thermostat up and take the load off the fitting. You could consider doing something similar.
