Overall Assessment

Customers highly recommend this tool for its prime qualities of being lightweight yet robust, ideal for lone work on heavy projects such as LS conversions. It is appreciated for its perfect fit and ease of use on vehicle fabrication and setups. Some users would have liked an LS thread pitch sheet provided for bolt purchase, however, it can be easily found online. Some suggested alternatives were out of stock, indicating this tool as a preferred option. The main feature highlighted is its practicality and assistance in mock-ups, especially enhancing productivity when working solo.

I'm currently mocking up three projects with LS conversions. This is a must when working alone. You don't have to wrestle around with a heavy engine. Just set this in place and get to work!

Using to set up a 1990 Isuzu pickup LS swap. Only thing that would be nice is the LS thread pitch sheet for purchasing bolts. Easy to find online though. Great product light weight and very strong.
