I am building a 56 F100 here in Australia, & am having trouble with building the tilt front hinges. It is a all steel front with no front bumper will be raised with electric actuators. I have seen pictures on the net, but I need some dimensions if anyone out there can help.

Usually the dimensions are dictated by the location of the hinges...which are usually mounted on top of the frame horns. There are various designs for these hinges and lift actuators so your specific design will have a lot to do with how you implement it. For instance, do you intend to keep the fender intact and slide the frontend forward before lifting or are you going to split the back portion of the fenders to allow a straight up lift without a forward slide?

Here are a couple of pics of one of the nicer hinge/actuator setups that I have seen...

I have a set of aftermarket chrome ones I took off my 56 that a PO used to make the front tilt I'm not planning to use. I think they came from Mid fifty originally (yes, part #1549). They bolted to the inner fenders and wind deflectors and pivoted on a bolt through the frame ears.
