There are numerous sites on the internet offering hydrogen kits for cars and trucks, with prices ranging from below $50 to  near $4000.  Some offer the manual and the actual equipment required. Other simply offer the manual.

Since the system is such a simple one and a fairly easy DIY job, I think you only need a manual. The actual components required are common everyday items that will cost about $100 in total so another reason for just getting the manual only and doing it yourself is the enormous cost saving.

Of course, further cost savings come when you have installed the hydrogen conversion on your car or truck. This comes with the amazing fuel economy - like cutting your fuel consumption in half.

With talk of petrol soon being $2 a litre and likely to rise more because of trouble in the Middle East, fuel savings should increase in the future.

Then there's the other benefits of the conversion, like smoother, more powerful running.

The source I recommend for the manual charges below $30 and provides a good back-up service.
