In other news I have bought some 306 compbrake top mounts and all the bits to go with them. So that includes the 2.25" spring top caps which i bought from ebay and getting the right size sleeve nut and washers that go with the top mounts. Bit of a mission trying to get the sizes but after talking to Grant, Puglove, Sam Moore, consulting service box and actually going out and measuring things I have worked out what I believe to be the correct sizes for everything... Ill put a guide together for this as I found it very difficult to find all the info.
Eccentric Top Mounts
You can use 205 or 306 ones. There is a bit of a different in price and it seems fairly ambiguous whether you have to drill holes or not. For the 205 ones you definitely have to drill holes but for the 306 ones reports are mixed. I guess it depends on how much rotation you have. The sleeve nuts and washers come with this. What I found is a lot of people talking about there not being enough thread to put the final nut on the shock. People have either had the shock machined with a lathe or had the sleeve nut machined. What the later versions seem to come with is a threaded sleeve nut so that this helps with keeping everything in place. Options are M12x1.25,1.5,1.75, M14x1.5 and M17. I did a bit of measuring and found the thread on my AVO GTZ coilovers was the m14x1.5 which is also the standard peugeot shock thread size. When they arrive ill be able to confirm that this is the right size.
i believe that some top mounts come threaded and others come without threads. The ones with no threads require nuts and bolts which makes it a pain for getting on and off the car.
Baker BM mounts need the chassis turrets cutting in order to fit. You can get half moons to weld in from some company somewhere. Also with the Baker BM mounts you cant run a strut brace as the bolt holes are different. You can cut the back half off the strut brace mouting to keep it.
Compbrake mounts are cheapest through their ebay store:

Spring Top Caps
Some coilovers come with only a ring kind of top cap. In order to run eccentric topmounts with a spherical bearing I needed a different kind of top cap. These have to be matched to the shock shaft size which is 17mm or 19mm and also need to match the Internal Diameter (ID) of your springs. The AVO GTZs use 2.25" springs. AVO wanted £30 posted for the pair of top caps. GAZ wanted £27.40 for the pair. Seeing as I didnt know what size I needed I ended up doing was buying two off ebay for £27 which had 10mm holes which can then be enlarged to the right size.
Very difficult to find on ebay unless you put the exact words in:

Will have to wait for delivery to see if what ive ordered is correct!
The Aim
below is an example of what the finished product you should look like. This is a gaz coilover with, very tall conical caps and 205 top mounts. Because the conical spring caps are very tall this reduces the thread for putting the top nut on. I Have gone for flatter ones which apparently provide enough 'conicalness' for the bearing to work.
