80 series Tow Point

Just been to ARB and they told me the only place I can bolt on a tow hook to the front is onto the bull bar plate on the bottom. This doesn't see very strong to me - as the angle is 45d to the vehicle. It's a Toyota Bar (made by ARB) but is not the same as an ARB bar. Apparently you cant bolt a tow hook onto the chassis where the bullbar bolts on as the thread spacing in the chassis is not the same as std tow hooks. The only suggestion he had was to get an origional tojo hook - but get this he said they were designed to be removed and not put back on when you fit a toyota bullbar as the upright plate is in the way - apparently on the ARB bar this plate is flush. Has anyone come across this before? Suggestions please...
