puffing and manged to loosen the header bolts, which alowed the exhaust to be moved out of way and get the swinger out. Great

Cleaned area up, got new swinger (all innards came with it - as its a brand
new arm), offered up the arm and bu&&£r me, it will not fit. Its too about
2-3mm too wide

So my question is, have I done something wrong or missed something out?
Has anyone else who did this have any similar problems?

What do I do now.... This is the second weekend of working on swapping the arm. Previous one took me fm about 1200hrs to 1800hrs to get the
damn lower exhaust off and 7 cutting discs to cut the damn chain links.
I thought this job was going to be easier than its turning out to be!!
