See the photo for how it is hitting on the sides. I took the bracket off the firewall and got it to line up on all bolts, but am only able to bolt down 2 of the threads. the cylinder that comes up the middle of the bracket, off the back of the booster is too fat.... Not sure what else I can do besides get another new booster from a different company. The midland booster that came out has a considerably thinner cylinder coming out of the back end...
