Long time between updates, again. I bought a house a few months ago so that has been taking up the vast majority of my time & resources but I have been trying to progress a few things in the background.
Front and rear wheel bearings have been replaced with new. I managed to find a machine shop to machine the front brake rotors (DBA DBA42355S for a Lotus Elise) to the correct centre bore (81.0mm) and PCD (4x103.0mm, 10.5mm holes) - this wasn't easy, quite a few machine shops won't touch automotive stuff.
I used the milkfab caliper adaptors for the Z32 (26mm) calipers - Z32 Front Caliper Adapters - Datsun 240Z/260Z/280Z (milkfab-engineering.com). Due to using the 26mm versions of the calipers and different rotors I had to use custom spacers. The adaptors come with 8mm spacers, but I found that 5mm spacers were perfect to centre the caliper on the rotor.
Before hooking up the brake lines and sorting out the rear discs, I wanted to get it back on its wheels and rolling so we could install a hoist in the shed. Turns out the Superlite wheels I bought are for later Nissan's and have a 66.1mm centrebore, not the 73.1mm CB to suit the 260Z. The wheels fit well on the rear but will need to be bored out for the fronts. I also found that with the bump steer spacer / roll centre adjuster that the steering tie rod hit on the inside of the wheels, so these needed to be removed.
Was great to see it back on wheels and rolling again. Also allowed some space to install the hoist which will come in very handy!
