Once you have the radiator support lined up with the fenders installed, you can get it spot welded back like the original one, or just have someone weld the seem of it to the chassis.
I have yet to get mine welded, I will eventually.
Let me make it very clear that its very important to do the swap when you have all the parts in hand, i had to wait for my fenders to get everything lined up, its best to get the fenders first they will help you align the radiator support
Here is a picture of the car with the swap completed
I hope this helps anyone who wants to do the swap.
if you have any question post them her or pm me.
