Hi folks not sure about this so any help would be most helpful Hope this will make sence ,i took my standard end cans off today but when it came to fitting it again later i couldnt get the stud hanger on the linkpipe behind the footpeg plate to insert the bolt

i tryed pressure with long bar but it just ant fitting .Now lads i have two ideas to what i may need to do please correct me if am wrong ,maybe i need to slacken of the main pin that hold the swingarm onto the frame to allow movement from my footpegs plate,then when on, tighten the swingarm and bring it all in .
or do i have to slacken off the down pipes /to allow me to line up the link pipe hanger behind the footpeg and them tighten up not sure so help please.
