Description
- Our patent-pending tab-and-slot version of the Swap Block Transmission Mock Up Block provides accurate transmission mounting and yoke positions.
- This unique design is lightweight and comes disassembled for ease of shipping and storage.
- One tool accomplishes accurate placement of a 4L80/4L80E transmission found in 1991-2013, 3/4 ton trucks and vans.
- Easily positioned by hand, there is no need to bench-press a heavy transmission into place for fitment and fabrication of crossmember, etc.
- Save time and money and work more safely.
- Durable steel construction resists heat from welding, so unlike foam blocks, custom crossmembers can be fabricated close to the block.?
