My mod is already old and I have not kept it after version 1.07.
But you can still open the pbo and edit the chkHelo.sqf script. There the anchor positions for the types of helicopters supported are defined. You just have to repeat the code of a supported version, changing its class name to the one of the MI-8 you want, but placing the correct values for the position vector (_datFastRopes):
Each element of the vector corresponds to a string position. Each position is an array of 3 elements that are the coordinates in the model space of the rope anchor (values x, y, z)
if (_tiptip isKindOf "I_HELI_LIGHT_03_UNARMED_BASE_F") then
_center = [0,0,1];
_datCam = [[0.67,4.45,0.2],[0,1, -1.7],[0,2, -6]];
_datFastRopes = [[[1.00,3.00, -11.95],270,1,1],[[-1.05,3.00, -11.95],90,1,1]];
