Heya - hoping for some answers to these questions:
Have the rear shocks out, U-Bolts cut off (they were rusted solid) and spring now just connected by front eye. That bolt is also seized (which I expected ). What I overlooked was replacement eye bolts.
 Is the correct 68 bolt 1/2" x 4 3/4" - do they need to be grade 8? UNC?
 Where could I get one of these in Melbourne quickly?
 Springs were just sitting on the spring clip plate - metal to metal. Shop manual has insulators(?) - do I need them? (pic below)
Thanks - have tomorrow as annual leave to hopefully finish this job off - any help on above appreciated.
Not sure on the bolts, but if you want an insulator, you could just cut some reinforced rubber to the same size as the flat on the diff housing and drill/cut a hole for the pin on the springs.
I didn't put one on mine though.
Any bolt shop should have them(or engineering shop - if you don't know of any , call whoever does your mechanical work for you , they'll know where to send you). They will be UNC & if you have the old ones , look at how many strokes are on the head of the bolt - it'll either be 3 (Grade 5 i think) or 5 strokes (grade 8 I think). Just saw that info mentioned in a posting somewhere on here recently. I'm sure just normal hi-tensile (grade 5) will suffice but Kerry will steer us all straight.
(PRAYER) Oh thank you Wild Turkey American Honey & Cola in those small thin bottles, for giving me the strength to act like a half wit, and say stupid things at inappropriate times, semi-anonymously, on a public forum.
If you have a bit of power, never use the insulators between the diff and the leaf. If you have a Falcon, pull them out and put Mustang lower plates in.... They are bad news.

Cheers donoauto - I checked total fasteners - they have grade 8 UNC 1/2" x 5" on their website - only about 6mm longer and can't see clearance issues with that so will call them in the morning. Just wanted to be sure there wasn't something unusual about those bolts given where they are, and I've yet to pull/cut one out
Tried your trick Moe - even with breaker bar with about another 1/2m tube - nothing budged. Bolt was totally corroded to the bracket. In fact everything was corroded to everything.
Learnt the following:
 I should have stuck with the angle grinder - started with it, but then tried reciprocating saw (as I saw a lot of guys in US recommend them) - no good - ended with angle grinder again.
 be less gentle - should have just cut the old springs off from the start to give me room around front eye. And bashing stuff with a BFH works.
 Cut really straight with thin cut-off wheels - otherwise they explode and scare the shit out of you.
 Make sure you have ALL the parts before you start - driving about trying to find stuff last minute burns hours.
So tomorrow the other side - then tighten everything up when it's down on wheels.
Thanks a lot for all the help and tips - really appreciate it - love this forum!
