(1) A clamp or vise is required to use the tool (not included).
(2) Check your local rules before drilling axle holes.
- Test fit the Pro-Body Tool on the bottom of the block with the two ‘ears’ positioned on the sides of the block. If the block is too wide for the tool, use coarse grit sandpaper to reduce the width of the block until the tool fits snuggly onto the block. If the block is too narrow for the tool, insert a piece of paper - folded as many times as needed - between one ear of the tool and the block such that the tool fits snuggly onto the block.
AXLE SLOTS ONLY: Mark the Block
- Use a square to draw a straight line on the side of the car starting at the middle of the axle slot, and extending to the top of the car (or measure the distance from one end of the block to the middle of an axle slot and transfer that measurement to the top-side of the block. Then use a ruler to draw a line from that measurement to the center of the axle slot).
- Repeat step 2 for the other slot. Then continue with step 4.
AXLE HOLES ONLY: Mark the Block
- Measure and mark the desired position of the new axle holes on the side of the block. Extend the mark from the bottom of the block to the top of the block using a square (or measure and mark near the bottom of the block and near the top of the block, and then join the line with a pencil and ruler). Holes for extended wheelbases are typically positioned 11/16 inch from each end of the block.
- Repeat step 2 for the other end of the block. Then continue with step 4.
Clamp Tool and Drill
- Position the tool on the bottom of the car with the two ‘ears’ on the sides of the block. Align the index mark with the line on the block. Clamp the tool in place, using paper if necessary to ensure a snug fit (see step 1).
- Hold the block firmly, position the drill bit in the hole, and drill 3/4 inch into the block.
- Without releasing the clamp, turn the tool and block over, and drill the second hole.
- Repeat steps 4 to 6 for the other two holes (or one hole if you will be making a raised hole).
- Transfer the line on the side of the block to the bottom of the block.
- Position the tool on the desired side of the block, and align the index mark on the tool with the line on the bottom of the block. Make sure that the third hole on the tool is positioned near the bottom of the block.
- Clamp the tool in place and drill the raised hole.
