For a shindaiwa t230 string trimmer. Drive shaft, tube, and throttle assembly. The tube, on the end where the trimmer head mounts to, there are a couple extra holes in the tube- can see when looking closely at the pictures. Not sure why they are there. The drive shaft splines look good. The throttle assemble looks to work as it should. There is an area on the tube that is worn from riding in a trimmer rack.
