Does anybody know where I can get some of the above bolts. They have to be grade 8.8. I went to change the rear suspension on the car today and the
ones in there have decided that they like the metalastic bushes and won't let go.

1/2"... unf i'm guessing, not as easy to get hold of as they once were. Either a good local nuts/bolts place or ebay, just make sure
they're a reputable distributor.

Give Namrick in Hove a call.
grade 8.8 is a metric grade, you will need the equivalent imperial grade
try

I have half inch bolts with 8.8 stamped on them, so they are available somewhere, but where I haven't a clue

When I needed some I went to the nearest agricultural supplier, plenty of old tractors and farming implements still use imperial bolts.
clarik engineering supplies, they have ebay shop and website of give rick a call, very helpfull , all my consumables nuts bolts etc come from them.
i bought the long bolts for my mx5 hubs from them for about £3 each
May be some here http://stores.ebay.co.uk/astleycomponents/HT-Hex-Bolts-Setscrews-UNF-/_i.html?_fsub=2785715014&_sid=684907314&_trksid=p4634.c0.m322
Why not buy a length of good (EN16 or EN19) 1/2" steel rod and put a thread on each end? You could choose between M12 or 1/2 UNF. If you get stuck drop me a line and I will make some for you if you do the measuring.

Err why is that? Not sure you have thought this through. If the bar is threaded both ends then the thread is a matter of choice. I tend to prefer UNF
as it is generally finer that standard metric threads.
The bar itself can be of whatever grade you choose. All bolts start as a bit of bar! If you are getting sniffy about a thread cut on a lathe as
opposed to a rolled thread then each to their own - I make my own head studs. Picture of a home made stud just to make the point!

Keep your hair on! lol 
I just prefer a smooth shank as long as possible through suspension/bushes and not a thread. As for replacing 1/2" with M12, fine if you want the
geometry to be different every time it's taken apart and re-assembled!.
No problem with screw cutting in the lathe over rolled threads, i do it all the time when i need to

Hair long gone
Actually I had assumed that these were long bolts. I was not suggesting putting 12mm bar in place of a 1/2" bolt but putting a 12mm thread or UNF
thread on each end(not the middle) of a 1/2" bar. No geometry issues at all.
It seems we misunderstood each other.
Sorry I should have said that you can get 1/2" Aircraft spec bolts from LAS Aero (it will google) - search the hardware section - they have tips on the part number for length etc - excellent mail order service
Thanks for all the pointers guys, one of the companies mentioned is only a few miles from me so I'll give them a bell.

you are sure its 1/2 inch and not M12 fine pitch thread? 8.8 indicates metric
