Hi Gadge, I have to reduce the body diameter, but I don't see it as a big problem as the body is a triangle and I will only have to take less than 1mm off it and then I can shorten it. I'm lucky they are long enough for me to hold them to take the diameter down. Bit tedious but seems like there is no other option. The ebay needles cost about $6 for 5 but out of that 5 you often get maybe 1 or none that work plus spend buckets of hours trying to get the mower to work or keep it working
