Why would you want to drill holes? Highly unlikely you will use it on the offside because if you do, you cannot fit the ALKO locks? In the years that we had our Lock n Level, we never had the need to use it on the offside. If the offside needed lifting, we used a ramp.I presume there isn’t a kit to do this, it’s basically buy all the parts the drill hole and fit?
We used a normal tyre compressor and plugged it into the 12v cigarette lighter socket in the car. Inflated the bag and job done.
