So do they fit or do you have to shorten them?

I raised a concern about this as the 135 vs 335 has less play depth wise when pushing the side shaft in hence the M3 one fitting in 335 depth wise. Someone has raised a concern in this regard that attempted the mod on a 135 and for unknown reason it failed. I cannot say 100% though. Worse case would be to give the M3 shaft a slight shave.
