Cheap stamped steel tool. Used once, already seen the worn chrome and round key points. Probably once or twice more work than a striptease. save your money
This is one of those specialty tools that just takes up space in your toolbox. Until you need it and are glad you have it. Much less needed these days as very few cars have distributors but I have used them 5 or 6 times and they are very comfortable.
These keys fit my 86 5.0 efi Ford perfectly. I had to change the timing slightly to pass the CA smog test and these keys were a workable one too Solution. I would highly recommend them as they don't require removing the air intakes. Don't forget to turn off the vacuum advance when timing.
