I finished machining the remote bleed fitting and hydraulic supply fitting, and they have now been welded. I have filed the hexagon faces back on and have fitted them into the slave cylinder.
I have also fitted the stainless braided hoses that go up to the chassis. With the machined fittings, I didn't have to modify the gearbox in any way.
Once this was done, I proceeded to mate the engine and gearbox. This is a bit tricky on your own, but it is nearly together now. I will get the bolts in to help pull them together.
