Started the tunnel mods needed to fit the Sierra gearbox. As I want to retain the ability to mount the factory 4 speed it's a little different than people suggest to do.
The oval cutout that'll allow either gearshift to be mounted. I have an alloy cover plate that'll fit over the top.

I've cut a little triangle out of the front of the original gearbox mounts. This is to give enough clearance around the 5 speed box.

Started painting the interior of the firewall. Didn't finish though. Need to buy more primer.

Here are the new rear U bolts all fitted up.

Next job is to make a rear firewall out of an old bonnet. Should be fun.
