I have made and fitted the final gearbox cover using perforated sheet. I don't think there are any more holes that require covering!

Starter Fitted
I bought a starter from GD since I didn't get one with my engine. It was a very straight forward fit (while the exhaust is off) but it leaves an uncovered part leading to the flywheel. I had to create another cover to ensure no debris can enter the bellhousing. I used the same perforated sheet as the other covers I have made. Only one more hole to cover which I will create over the next few days hopefully.

Gearbox Plugs & Covers
I remade one of the covers using more perforated sheet to provide some ventilation. I still have a cover to make on the N/S of the gearbox, and one around the starter motor. I have received the starter, so I'll bolt it in place and make a cover to suit.
I bought a mechanical speedo plug from Roadcraft UK, removed the shipping bung and fitted the new plug using a M6 x 16mm set screw.

Another Flywheel Cover
When I told Andy at GD that I was making covers for the flywheel / gearbox, he said to me "Make sure you leave plenty of ventilation".
If you refer back to my previous post regarding the flywheel cover, I made an aluminium cover.
Rather than drill holes in the aluminium cover, I used it as a template to make one from perforated sheet instead.

Just a couple more to do!

Coil Packs Installed
I have fitted the coil packs to the rocker covers and connected up the spark plugs. For some reason, the mounting holes didn't quite line up and so I had to open out one of the holes on each frame. All done now and just waiting for the engine wiring loom to be fitted to complete.

Exhaust Manifolds
I bought my exhaust manifold gaskets from Monkfish Performance to fit my GD supplied exhaust manifolds. The gaskets can be found here.
I used stainless steel set screws with spring washers and washers to fit them.
I will have to modify my trestle supports to be able to fit the remaining underslung exhausts. Watch this space.

Gearbox Connectors
I spent a bit of time trying to find the correct connectors for the Tremec T56 Magnum gearbox. I have managed to find them and I have detailed them below.
For the Vehicle Speed Sensor (VSS): Dorman 645-213. This comes complete as a pigtail connector and will require soldering in place. I bought mine through RockAuto from here, but there are other suppliers available.

For the Reverse Light Switch: Delphi 12015792. I bought mine through SimtekUK from here
For the Reverse Lockout Solenoid: Delphi 12052646. I bought mine through SimtekUK. They don't list it on their website yet, but if you contact them they will supply.
