I assume that is an early type 1 swing short axle trans . You will need to find 67+ long axles and tubes , remove the trans and swap them (using your bentley manual). You will need a trans gasket kit , 2 axle boots and 2 axle seal kits and you may need additional axle spacers so that you can tighten up your early drums . As for mounting panels , when we built ours we welded tabs around the inside of the tubes anywhere we wanted panels.
