I agree. Making two mirror image adapter brackets would require some very precise measuring and workmanship. Some kind of jig would be needed to hold the critical parts in alignment. An advantage of this approach is that you could change the geometry at a later time by fabricating another set of brackets. With enough adjustment built into the wishbones, it would be relatively simple to swap street geometry to track geometry.

Let's see if I understand you correctly. The E30 and E36 small diff rear covers are interchangable and the E30 & E36 medium covers are interchangable. And the small cover won't fit the large case. Right?

What do you know about the Z3 diffs? It looks like they have yet another version of the rear cover. I think it's the same diff. Is the cover also interchangable?

Bob.

Thats right as far as i am aware.

The Z3 uses a nearly identical rear end to the E30. Except with 5 stud hubs, bigger brakes, some new diff ratios and the option of a very tasty 'torsen' diff.

The diff is indeed the same except with that nice finned rear cover. This cover should fit any other similar aged medium cased diff. E30 E36 E34 (small engine 5 series) etc.

Any more questions?? :D

Mind you, i am just about to go and double check about all this.

On my car I have trial fitted an E36 diff and have moddified the chassis mounting points to suit. The E36 rear hubs have been modified ( a lot of work) and the upright design modified to suit. The hub mods require a lot of material removal with angle grinders than time in a lathe so the final design looksa bit like a standard Ford item.

Sounds cool :)

Why not post a few pictures to wet our apetites ;) :D :D

I've tried but I'm a bit thick and cant figure out

Tis quite easy once you get the hang of it.

This is how I manage

Use a photo sharing site such as Photobucket or Flickr or the likes

Plenty out there & free to use

Upload your images to your chosen host.

I use Photobucket, it will allow you to resize the image when you upload.

Once the image has been uploaded, look for images code ( Web address ) .
Should look something like this: http://i274.photobucket.com/albums/j...e/100_0269.jpg .......Will have [img] either end though.

Right click on the image code & choose copy

On your forum post, click on the insert image button on the tool bar at the top.
You may be prompted to allow scripted windows ( I do )
Click on the prompt & choose to allow scripted windows.

Click on the insert image button once more & right click on the text box that pops up & paste the image code in the box. Then click ok.

This should bring up a photo within your post.

I believe that you can post images that are on your computer.....Don't know how to do that though :o

Probaly easier ways to post photos but it works for me :D

It might just be me but I can't see anything apart from little red squares!:confused:
