In other words Nick, you need a 12g1128 casing with hardy spicer outputs and output covers with an 18 tooth 1st motion shaft and 1040 laygear. The 1040 laygear is sometimes marked with ME instead of the part number.:)

The 12G1128 casing is the easy bit. The hard bit will be the diff outputs and covers. The 1st motion shaft and laygear are available new from MiniSpares.

Yes but there are versions of it you want to avoid, like the ADO16 etc.

Good point Pete.

So avoid any casing that has the bolt holes for the remote on the side of the diff housing foot.

Nick, if you're still looking I have a 22G1128 box with 22G1040 laygear and 18 tooth 1st motion shaft. The diff case is there but unfortunately no diff / hardy spicer assy. or end plates. You can have it for a ' fair price ' ( whatever that is ?? )

Nick, if you're still looking I have an 1128 box with 12G1040 laygear and 18 tooth 1st motion shaft. Diff case is there but unfortunately no diff assy or end plates. The case is also stamped FAX 1797 ( not sure what that means ). If any good to you you can have it for a ' fair price '( whatever that is ) ??
Cheers
Dave
PS There's a pair of Hardy spicer diff output shafts on ebay at mo for £95
