993 ABS sensors and strut mounts
Also when converting to 993 uprights ABS sensors from early 993 (p/n 993-606-404-00) should be used - they have different orientation from 964.
Also bolts #3 & #5 parts from 993 need to be used. 964 parts will not fit.
#3 (p/n 999-072-006-01) M14 on 993 and M10 on 965
#5 (p/n 999-067-039-09) M12 on both but pitch is different .
