I have a 2000 Mercury Grand Marquis and I know that this may sound a little crazy but I am trying to cut the top off to put a removable roof City on the frame but in order to do this I know I must stiffen up the frame I have seen some cars have a support bar in the middle of it I think they call it a sports bar will that be sufficient enough to keep car from bending when making a hard stop and will it be enough to stiffen up the fram to support the roof being removed
