Personally, I would split the box, then tape the mating faces, block off the internal castings and use the mildest blasting media available. The split is the easiest part of gearbox disassembly, just leave the innards attached to the sandwich plate and remove from the equation. You can clear coat the castings but if the vehicle is run hard regularly, you won't get oxidation.

The only thing is it's a new box so you may be reluctant to break the seal, so maybe try some alloy cleaning products and elbow grease?

Thanks Andy,
I think i will go look for some good alloy cleaning agents as you said and finish it off...
to be honest its not to bad now after kero/turps/crc + elbow grease... but a few small areas could do with a further spruce up...

Thanks Bernie.
Here is the fuel cell area.
Not perfect, it looked a bit better in my head, but will do for now...
Once work places open i can get a flange welded onto the fuel inlet cover tube... and then bolt that up.
Just need to fit the diff oil cooler pump into the box and plumb it up, again waiting for shops to open next week so i can order online the remaining bits.

Box from Ulrich Aluminium Fabrication

Filler tube in progress... i had to by 2.5m of tube... so got a lot spare. :P

Lift pump & main pump plus filters.

Oil & Fuel lines...

That's a really awesome idea. Maybe we could do a garage tour as we did a while back, only available to financial club members.

Keep up the good work Grant, getting closer and closer to being a going thing.
Next - Z Club events:
= Once things settle we'll get som events, check out events page or our Z Club NZ Facebook page when we're to Level 2 or 1 =

Thanks Guys, hopefully by summer it may be alive!.
Diff Oil Cooler pump work underway.
Have all the fittings except the ones that go in the pump, will order those tomorrow, along with a inline filter.
Just need a bracket made to mount the oil cooler, so will get that underway tomorrow as well.
Last photo is the space where the cooler is going.
They didnt have the size i wanted so settled for a smaller Setrab unit. My engine oil cooler is the same make, just bigger.
Pump is the Tilton intermittent version.
Fittings are all -8 AN.

Fascinating watching it all take shape.

Next step in probably a few weeks is to get the headers made, and i need to get a dummy engine in for that along with the gearbox.
I have one in my garage but hoping to find one of my other spare engines up at Reg's which is all stripped and clean.
Once headers are made, then they can go up to Reg's for final engine assembly... and when he is back from Bonnyville (assuming it goes ahead) then dyno time...
Maybe when this is happening car will be getting some of its body work fixed, not to be made perfect, but at least to fix some problem areas that were rushed due to circumstances a few years ago...
So i am hoping it will happen this coming summer, or at least the end of summer...

However the list of little things to do seems endless, as everything i touch takes a few weeks... and suddenly half the year is gone.

The other one is i will probably get someone to do a head to tail new electrical loom, plus breakers, switches etc... not sure who yet.

Are using the old loom as a guide, if so do it yourself. You have samples of wire thickness, lengths you need and you can buy the plugs. You could use newer plugs we got a bunch from AliExpress, just check the brand you need so you don't buy rubbish, then all you will need is a good crimping tool also available on Ali. That where we got ours. My advice is to solder all the joints you can.
