FRONT SUSPENSION TOP MOUNTS - NIGHTMARE!!!
I've not finished the build yet, but nothing has come close to how hard that was. I got them in from the inside (and in hindsight, I think that the front top mounts should be done before the wishbones to allow a bit more access) but my mate who is also building an Academy car deformed the Ali skin inwards and got them in from the outside. Quite a bend ...
I also took a very thin layer off the fixing spacer on the inside, to let the bolt through more easily. I couldn't push the bolt through by hand before doing this. Total time for top mounts 4-5hrs ☹️
Re: gearbox oil, I spoke to Caterham about how they do it, and they fill it before it goes in to the car, and then plug all the holes up. My mate put the oil in before locating the engine/gearbox while I cut down a straight 1cm piece of 10mm allen key and then used a ratched spanner onto the cut-down piece, which was pretty easy.
Other struggles have been in relation to the diff, but I followed the advice on here, and suspended with screwdrivers at the top while locating the bottom, and didn't find that any harder than most parts of the car! You need someone to locate the first screwdriver while you are lifting the diff though
