Either that or make up a datsun specific variant of what Ford called the World Cup mounts for the Mark 2 Escorts, Basically what they did was made up a mount where the actual rubber was a Ford Transit leaf spring rubber the big one at the front fitted it into a tubular mount and then ran a through bolt such as an Unbrako through it and througn a couple of Tab mounts set up on the chassis.

Or make the mounts on the crossmember and the tabbed mount on the engine the linked page shows the detail basically unbreakable but still rubber isolation for vibration much better than solid mounts.

One other thing to do every time you replace a synchro cone make sure you tape up the gear leaving just the mating cone section exposed and then get it glass bead blasted for after a while they polish up and the friction required for good synchro operation is lacking.

This makes a vast improvement in synchro operation, Even works when you don't replace the Brass synchro cone on the other gears so when the box is apart glass bead all the synchro cone mating surfaces on the gears.

One of these would be nice an LZ 16 in a 1200 coupe and the following video after the LZ engined 1200 coupe is the infamous crossflow A series TS Cup car.

That Engine will never make massive horsepower as such with the Z18 ET head but it will make stupendous torque and when all said and done torque is why people like V8's, None of that 1234 can we go now stuff torque means it goes now when you put your foot down.

Ran a Bluebird Turbo years back and while it did not impress with Horsepower figures it did make some 400 Ft/Lb of Torque at 3000 RPM so you know what to expect.
That bear in mind was a 1770 cc Engine built to strict class limits as well running a rebuilt stock Turbo T3 Nissan part.

Custom Made my butt Maddat is probably just sourcing a stock 120Y B210 Booster out of India where many brake parts are made nowadays.

People forget that just because they stop selling something in your country does not mean they stopped making them, such as Bakkies in South Africa early Suzuki Swifts in India and Pakistan, Old Yamahas in Taiwan and Old Suzukis in Thailand and the most amazing one of all,The Original old Ford falcons from ther early 1960's XM and XP models were still being produced and sold in Argentina up till 1996.

When you know those sorts of details parts supplies can become a whole lot easier.

Oh and your teacher was useless it is Brake not Break

Other options maybe Spanish Braid Wheels custom so diameter, offset and width wharever you order and they have a local agent in South Australia though he probably only brings in the late rally wheels but explore the homepage and look at some of the classic ranges .

Some nice classic no longer available types on page 4 even in the South Australia distributors webpage that are new copies of some classic Japanese styles that are unobtanium

Ah Guys a 63A is an L series gearbox not an A series and no it will not bolt up without a lot of work, The A 14 Five speed you need is a Type 60A, The other five speed was the direct fifth A 12 GX Gearbox which basically had the same ratio spread as the normal A12 Four speed but with five ratios they were all closed up.

Both will be getting hard to find major parts for if you break them though and the A14 type 60 Five speed is a bit stronger obviously than the type 56.

If all else fails it will destroy the nut but whar is known as a "Spring Loaded Speed Wrench" will get them undone because it uses a swivel spring loaded design and the harder something is to undo the tighter it grips.

The smartest thing anyone can do before they respray a car is to make sure there are Photo's of the original condition and stage by stage of any repairs.
Doing that means you have proof is was not just a dodgy repaint over a death trap rustbucket and will greatly aid getting a good price down the road if or when you may decide to sell it.

People will appreciate good paint if they know what is underneath is sound or properly repaired and the price will then be appropriate to how good it really is rather than what it looks like.

It does not take much effort and many forum members of different forums do exactly that in a build thread and it pays off when people can see the effort that went into making it a good one for then they will pay a fair price.

A nice option for road use because Spherical bearings can rattle and drive you nuts is to shorten up the spring perch and make a flat plate top mount to suit the car and then get hold of a pair of S30 early 240~260Z front strut tops and offset the mounting points on the flat plate mount on the strut tower to where you wish it, The plate is required as an adapter because the Zed tops are much smaller than other datsuns but bolt up to your strut shafts OK.

The Zed tops are a much smaller diameter and allow more leeway in locating in the strut tower but are best used with 4 inch diameter spring conversion at the same time and are low maintenance items that live real nice in the real world for a road car, Oh and they are firmer rubber than the average Datto as well as more compact so a nice road mod that also works OK for occasional Motorsport use on tar and perfectly reliable off road for rallying.
