Yes that will definitely help get in it but you have to do it pretty quick.

It is a good idea to polish the rust out of the bore. When installing the new bush, use a grade 8 UNF bolt. Lubricate the thread. You will need multiple bolts, of different lengths, or a set screw if you can get one. You will need to make a mandrel to press on the edge of the bush, so as to not dislodge the inner from the rubber. You will also need a plate on the rear, with a recess to accept the centre of the bush.

You might find a socket from your socket set may be just right, too.

Yeah thanks Aaron that's pretty much what I have done. I'm hoping that if I cut the bush out and start again I will have more luck. I have several unf bolts, silkolene copper lube on the threads and I found a socket that is just a fraction smaller than the bush so it pushes perfectly on the outer.
The next job is going to be the leaf spring bushes, any tricks I need to know?

See my comment above about using an air chisel.

The bushes in the springs are easier because the spring eye is springy. Driving a cold chisel slightly into the space between the eye and the top of the main leaf will help, but should not be necessary.
