similar to the factory one with the threaded end so a wing nut can be used to pull sttuborn valve bodies-you need to use a 2" spacer against the back of the tube for the wing nut to act on
I can supply a delrin or ally one but it all adds to the cost -I've only ever had to resort to using the tread once on a crusty 347 as most times the valve body comes out with a wiggle
