I soldered some brackets to the sides of my radiator to bolt in the stock holes. Never replaced the support and never seemed to be any issue that I noticed.
I was going to leave it off at first but after a little thinking I figured it would be best just to keep it in place because I have no way to get brackets to hold the radiator and the radiator is not in the stock location. It has moved forward about 3" I believe. The sides that the headlights bolt to were pretty flexible on my car so I figured it would be best to leave it on because of the additional power and everything. I just hope I will be able to get all of the air out of the system
