Finished deburring and fitting the remain angles and gussets. The firewall components are now ready for match drilling tomorrow night. Notice how the side angle goes on the inside of the lower engine mount weldment (second photo: a little hard to determine from the plans. You have to kind of wiggle it in there a little. I noted that the side angle was not allowing the weldment to slide into the correct position. I had to relieve the side angle on both sides a little to clear the weld in the corner of the weldment.
