The 1260 closer body has the same footprint (9-1/16" x 3/4") and it mounts in the same location as the 1070 body, but the arm will have to be moved slightly to match the 1260 templating.
The P1070 was replaced with the 1261 Rw/PA.
The 1260 arm can be used as a replacement arm for the discontinued 1070.
The P1070 arm can be used on a replacement 1260 body to maintain the original templating.
