Congrats on getting your wheels and axle casing and I'm impressed by your fortitude regarding the lights - I shall be pursuing the alternative method! 

How something as simple as gearbox and diff oil becomes a problem is beyond me; Shell products are not unique so surely they could provide a list of equivalents, let us buy it in the small quantities that other producers seem to have available and then provide a refund. Noting in the handbook that the diff oil needs replacing at 3mths - do they think (after our current experiences) that we are going to go back to Caterham to get it!  

Hi Simon - I didn't take anything off the diff before fitting. Looks to me like you might have some sort of 'transportation keep' in place that is retaining the half shaft bearing. I can't recall if there was one on mine; if there was it's in and diff turns OK. Mine you fitting the diff is quite fiddily; it only goes in one way, drops to about an inch from mating and then has to be turned and juggled a bit to align the main wheel with the casing space. Trouble is, I reckon if you don't have the sealant in place and do a 'dry run' it will be a devil to get it back out to add the sealant. 

I will look at the front wings tomorrow and yes, having read of wings flying off at inopportune moments 'I've decided to bolt mine as well, so I'm just as interested s to where the marks are. 

Looked at this again and blew up the picture of the diff in the assembly manual. It looks like those bolts (and whatever it is hanging off them) should be there.

You must be a mind reader, I was thinking exactly the same as per the rad. In fact I have asked Derek whether anyone has ever suggested cutting the repeater wire so you can load the Econo plug with a 'rats tail' and then re-join the wire with a single spade connector just inside the upper wishbone where it comes into the body. This would mean the wiring is done and dusted before the rad goes in and also make changing the cycle wing easier.

Simon - I have no marks on my wings for the 1st holes; only for the repeaters. In most phots it looks like the front stay aligns with the middle hole of the repeaters. Good luck and I will be following your every word!

Although the diffs are similar this one is from a little van called an Every. Just in case you are going to go trawling for LSD's or any other parts. Jimny wont fit.

Im sure there is a locator mark underneath, when I built a SV175 . 

you really do not need to drill and bolt, you would never move my wings which are Sikaflexed on.

For Ned and others in line - Re access for wiring Econoplugs once the rad is in.....................I measured up and cut the wire from the repeaters and made a 'rats tail' with the free end. I then crimped a female 'bullet' connector on the end and wound the wire with heat shrink tape, fitted it into the econoplugs with the other 5 wires (not all coloured as the manual says I might add!), ran it up a heat shrink length containing the other wires so it comes out where the other wires come into the body, then tie wrapped it aft to just inside and above the upper wishbone. It waits there now for when I get my wheels and can fit the cycle wings. The tail coming from the repeater will get a male 'bullet' connector crimped on after threading through the wing strut. It will then plug into the female. Meanwhile I can get on with fitting the rad and intercooler without worrying about access to tidy up the wiring.  And if I ever have to renew a wing it will be v easy to disconnect the repeater, cut off the bullet connector and withdraw the wire without disturbing the Econoplug. Not rocket science but 'every bit helps' as they say, and it might solve a similar problem for you.
