I'd make the balljoint plate more triangular and just fit one more bolt like a lot of pressed steel bottom arms use

yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Thanks for the continuing advice. I've been starring at the car all morning and may have come up with the conclusion the Zimmerframe shocks are
too long. My ride height at the front is 7.5 inches and 6 inches at the rear. I got SWMBO to stand on the front end this morning (not impressed - all
dressed up and ready for Xmas shopping!) and the front dropped by nearly an inch...(okay you boffins how heavy does that make my wife??).
The Zimmers measure 13inches centres in their current position.

Thats what I was talking about. I would't wory about the shocks till the weight of and engine and radiator were installed. Generaly you want
the lower arms to be paralell with the ground at rest and the tie rods should be paralell with the lower arms.

I'am less worried about the shock length than I am about the angle of the steering arms.
Even with 140Kg stood on the front end the ride height only changes by a single inche.
I might try and wind the huge bolt up on the Zeemerides to see if that drop the ride height enough to make a difference. Any idea where I get a
spanner that big from!?

goodness me, lots of things here!
Firstly, take the shocks off again, and jack the car up under the front of the chassis at your intended ride height (which should be with lower
wishbones pointing slightly downwards towards the outer ends)
Then set front tracking paralel.
Then drop the jack 1" and see what happens to the toe-in/out. Then raise it 2" and see what happens to the toe-in/out.
Looking at your rack position it will probably vary quite a bit.
I am purely guessing but the rack looks like it needs to be quite a bit lower to me.
You will have horrendous bump steer set as it is now.
Once you have that sorted, then work out your shock lengths, which on a bookish chassis with bookish wishbones will be 12" on the front.
13" are too long.
Throw the zeemerides in the bin, they are a waste of time entirely.
get 230-260lb springs for the front end if you are using a crossflow, put on your 12" shocks and set the ride height.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning
