i figured it outtttaaaaa the M69he and the m67 nade's fall under the same file that's why i couldnt find it anywhere in the folder, if you want the m69he to be a chicken leg also its reallll simple
Extract GUNS_T_HH
Take the texture file from my HH t folder open it with hex edit
Now Find m69he in the GUNS_T_HH folder you extracted
Open it with hex edit, copy and paste my code over it ..exit Done
Rename the file an your good.
