If you look at your picture you will see 3 linkages with eyelets on the left side. These are the shifter linkages. The standard 113 transmission has its linkage on the top of the transmission. This transmission will not fit into the transmission tunnel opening with this side shift setup. The transmission mount will be too far back as well. With enough work, anything can be made to fit but in this case you would be cutting and welding the body to do so. Not worth it. A Getrag or T-5 conversion would be more cost effective.
