96fifolt1

I am parting out a 96 Firebird convertible that has a V6 and a automatic transmission. I noticed what appears to be a frame or body support directly under the car that is shaped like a "X" and is attached to the body and crossmember. Will this support work in my car? It is a 96 Firebird Formula with a LT1 and a 6 speed tranny. I looked under the LT1 car and the crossmember does not look like the one that I took out of the convertible. I guess I am just wondering if the setup out of the automatic V6 car will bolt directly into the LT1 6 speed car without any modifications to help give it strength thanks for any help J
