Great tool, this is the one to buy
Had to replace my balancer on a big block Chrysler engine. I had neve done the job previously. I watched you tube videos so I had an idea. My dad always said "Use the right tool for the job", well this is the one. It made pulling the old one off and re-installing the new one easy as pie. It comes with instructions in the nice organized plastic case. I highly recommend this tool

Hello. I understand this puller/installer set is not vehicle specific, but does anyone know if it will work on a 1978 Chevy 1/2 ton K10 Pick Up - 350 cu. in./5.7 liter, small V8 engine? The manual states to use tool J-23523 for removal and installing a torsional damper, but I'm having trouble finding that specific tool. Thanks in advance for any help!
