So it's been a while I know. Thing's have been progressing slowly. Working FIFO and having 2 kids limits the time you can spend on these things. Figured it's time for an update anyways.
After finishing the front and spinning the car round I though I'd start on the bushes in the rear. I attempted to use the threaded rod trick to push the old bushes out of the rear control arms with no joy. On my last stanza we ended up using a 200 tonne press to get them out. I ended up having to take them to a suspension place to get the old bushes pushed out.
While this was going on I sold my old turbo setup to a local bloke.
I had been thinking about the rear brake setup and my brother convinced me instead of just doing an rear disc conversion to put a complete diff with brakes in. So I started searching for a complete R31 skyline diff. Now as it happened in conversation while selling my turbo setup. The local bloke aka skitzone aka Hayden mentioned he'd picked up an LSD diff to put into his non LSD R31. So after spending an arvo helping him put the LSD into his skyline I picked up a complete diff for $100 bucks.
After getting it home and stripping the mounts off the skyline and stanza diffs I set about shortening the skyline diff. I'm going to be running 15 * 8's with 0 offset, and getting these to sit neatly inside the original guards without too much work was my goal.
After some careful measurements I figured cutting 50mm off each side would get the diff down to 10mm below the original lenth of the stanza diff and hopefully get rims to fit inside the guards. It took me quite a while to get the mounts in the right spot as I used measurements and marks to get the mounts right. If I had to do it again I'd build myself a jig off the original stanza diff. To get the ends back on I bought a piece of 24mm round bar, got some bushes turned up at a local machine shop and used that to make sure everything was straight. Here's the diff fully welded and cleaned up. I'm going to get it blasted and either painted or powder coated. I've still got to drill and tap the breather in. I'll get the blasting and painting done after sorting out all the mounts for the hand brake and brake lines.
I purchased a R31 handbrake setup off ebay. The stanza handbrake come's out the handbrake and goes through the floor at the back right hand side of the tailshaft tunnel where the skyline one goes through the floor in the centre and into a Y piece to a couple of cables out to the brakes on the diff. Like this.
What I'm going to do is use the stanza hand brake lever. With the skyline cable through the floor into the skyline Y piece and then get shortened cables from the skyline Y piece out to each brake caliper. Here's the skyline hand brake cable mounted in the floor of the stanza. It actually fit extremely well. Just reqired an elongated hole and a couple bolts. It fits straight into the stanza hand brake lever. Just needs a couple bolts and it'll be in. Then to mount the Y piece under the car!
So that's where I'm up to at the moment. I need to source a pair of 28 spline R31 skyline axels. If anyone in perth has a pair I'd be glad to take them off your hands. Then I can get them shortened and start reassembly. I've got to get the calipers rebuilt as well but that will happen soon too. I'll leave you with a couple of pics of how the rims sit on the shortened diff. Will still need to roll the guards but the sit in a hell of a lot better.
