Not huge progress this weekend. The old engine and gearbox have gone to another home which is another job off the list. I managed to get the gear linkage fitted and connected to the gear cables. As part of the conversion you need to remove a linkage part from the original MR2 gear box. It has 2 arms on it and basically you have to remove one of the arms and weld a new arm on, which is supplied in the engine mount kit.

One of the arms looks like it has a fixing on its face while the other arm has a smooth face, I took an angle grinder to the arm which looked like it had a fixing. The arm with the hole in it, you want to keep the arm with the stud for the cable. It took a while because I was being extra careful with the grinder but eventually the arm came off. The new arm is a nice snug fit over the stub that's left, this needs to welded into place. I was going to farm this out to an professional but I got bored and had a go with my trusty 25years old no gas mig. This worked a treat so it was ready to fit the Audi gearbox.

As part of the engine mount kit there are a couple of bearing races that replace the rubber bushes on the end of the gear cables. When I attached them to the cables I used M8 washers to shim them where they attach to the gearbox. I assembled the cables and linkage without the washers first to work out the best position for the cable to keep the cables as inline as possible.

There is a plate that is supplied that bolts to the top of the Audi gear box to enable the modified Toyota rocker arm linkage thingy be to attached. Once these two were bolted to the box there's a rose jointed rod that connects to the Audi gear selector and the modded rocker. There are 2 new brackets that hold the outer gear cable, one of these bolts to the engine mount and the other bolts to an existing threaded hole in the gearbox. The cable that goes to the modded linkage is for the backwards and forwards movement of the gear stick. The cable that goes to the engine mount mount is the one that does the side to side movement at the gear stick. I can now sit in the car and select the gears. They do seem a bit close together side to side but I plan to mod the gear lever at some point to improve this by giving it some more side to side throw. There is also no gate to stop you selecting reverse but I can't see this being a problem. If it is I'm sure I can come up with something.
