Ford CMP 8cwt Rear Springs

[david moore]

Advice please!
The rear springs on my F8 definitely need new bushings - I can get spare bushings from Mac's Auto, no problem. But how do I get the shackles apart?
I got the locking pins out OK but the main shackle bolts seems to be screwed in place and have a large slot at the outer end for , presumably, removal by a monster screwdriver - but they are solid even with plenty of heat supplied. There is nothing mentioned in the F8 manual to tell what the design of the bolt is like i.e where it is threaded into the hanger- and the later 1943 manuals (that don't mention the 8cwt) have a completely different type of shackle bolt shown with convenient nuts exposed at each end just like my front ones are..

If mine are supposed to be driven out, no way since I can't get to the back of them.

Advice or help greatly appreciated!
