I own the tool.
What you will find out is that it more than three metal things put together.
The business end {anvil} is removable and works in both directions. If the machinist time is $40 per hour You will easy spend more than the Performance Prod. price with labor and cost of steel stock.
If you plan on keeping car and need a chain every 150K or so two rentals and shipping will almost pay for the tool. Also Larry method does work with hammer and dolly.
I have three car to spread the cost of tooling over. That's why I bought it.
Good luck.
