No, the 66mm and not the 61mm. 53mm is the front buggy shocks
I'm unsure exactly of what the "Red Army" is running on the rear of the MP9 for length now, but when they switched over to the shorter rear shocks they originally went to the STRR front which is 61mm.
For your 777, go with 53 (IF349) & 66mm (IF346) lengths.
Note; Those part numbers are for the original non-velvet coated bodys.
