All you could need in the way of Belts and Pulleys, compliments of Rick. Quote: "Try here: https://sdp-si.com/eStore/Catalog/Group/217# In the left column: Pulleys > Metal timing pulleys and: Belts and Cables > Timing belts Under the Pitch column, you'll note the GT2 pulleys come in 2mm, 3mm, and 5mm lobe spacings. What is referred to here as a GT3 is actually a 3mm GT2. Many Thanks. Gray
