You are probably correct, I have added extra bracing to both the longer tabs but maybe its worth doing the same on the others too.

So tomorrow's task will be to make and weld on 12 of these.

A very long day in the garage but probably my last for a little while as I need to spend a bit more time on other things.

I ended up making 16 gussets to add strength to all the control arm mounting points, the extra weight of the gussets was 375 grams.

A bit of a production line.

The smallest ones were just to finish off bracing the lower rear control arm mounting point.

The next size up were for the base of the toe arm mounting points.

All the rest were the same size and were added to the upper control arm and trailing arm mounting points.

I then went over all the welds with a series of wire brushes in my cordless drill. Following that it was all wiped down with wax and grease remover and the areas where I still need to weld to were masked up.

Then I painted it will cold gal to prevent any surface rust forming whilst I complete the build.

So that's it for now, it can go in the car next but as I said I'm going to take a little break first.

What's the plan to lower the raise points in front, are you building a new front subframe as well?

Yes a front frame will be required too. This question was asked previously, see here http://www.ft86club.com/forums/showp...3&postcount=75

Just weighed the frame:

Stock frame 24kg (53lbs)

My frame 16kg (35lbs)

Pretty good weight saving so far.

Looks like good progress was made. I like how you are building this car!

This is like one of those shows you want to binge watch. You go to the inter webs and realize there’s only a few episodes out...

Great build. Thank you for sharing.

Hey guys, does anyone know how to remove the front diff bushings? There is a metal lip on the underside meaning they can only come out in one direction, so my usual arm pullers are not working and I don't have a press.

Has anyone had success removing these?

Heavy Hammer, and a socket was what I used.

You could also use a pipe to fit the opening on the large side with a heavy washer on it then a smaller heavy washer in the opening on the smaller side. Run allthread through it and tighten up nuts on both sides until the bushing slides into the pipe.

Thanks guys, I just wanted to confirm it was a standard press in bushing and I wasn't missing something.

Zer0 · 05-15-2018, 02:19 AM

Yep just a press in bushing.

Hi Guys,

I have had a little break from the car but got started again today.

I got the diff bushings out and am in the process of making some solid mounts to replace them. Next job was getting the rear end of the car ready to install the cradle. I started by removing some of the bracing around the shock mounts as I will need access to this area to fabricate the new mounts. I also removed the bracing above that as I kept bumping my head on it.

Lots of spot welds to drill out but the operation was a success.

I will show what I did with the front diff mounts later on when they are complete, I am waiting on my friend to turn up a couple of bits of aluminium alloy on the lathe as spacers. The spacers are not straight forward as I have limited space between the upper and lower tubes and therefore had to make the heads of the nuts recessed.

Here is a little sneak peak of the next step.
