Williams/172 shared parts

[rickyquicky]

I'm breaking a ph1 at the moment and took the wishbones off today, when i saw them i was surprised how much they looked like the ones on my williams.

Put them side by side with williams wishbones and they look identical!

Can anyone confirm if this is the case?

If so what other parts are shared as im currently restoring my williams and knowing which 172 parts fit will be very handy!

nothing is truly interchangeable, but you can bolt the whole 172 track onto a mk1. But mix and match it won't work due to bolt sizes, hub widths and other niggles. so a hybrid of both would be awkward.

As said, none of it is a direct swap.

Isn't the 172 running gear wider than the williams if i recall?

 

[rickyquicky]

Thanks for the replies, so what about the wishbones then? Im sure they were identical.

In fact im going to take a pic now anyone know a quick way to upload photos from iphone?

172 ph1 wishbones are identical to williams i just checked again.

Struggling to upload photos will do it tomorrow when i have a desktop computer.

Im interested in this as if it is confirmed i can buy brand new wishbones for a reasonable price including new bushes etc

If you have two to compare in front of you then trust your own judgment.
I don't know if they are the same or not.

 

[rickyquicky]

As far as I can see they are identical in every way?

 

[mad in general]

It is a bit hard to tell but they do look different in the angle of the ball joint bolts. This would change the caster angle.

I dont think the ball joint bolts are different, I tried to get the balljoint off the williams wishbone but one of the bolts is a bit seized so I didn't bother.

If the angle is different it will be minimal as you can see in the pictures but to me they look identical.

The concensus seems to be nothing is interchangeable, but the rubber bushes are the same, widths and spacing of everything is the same, bolt holes, anti roll bar locator is the same, this part is interchangeable unless I am missing something?

Also of interest is the rubber gaitor for the gear linkage joint under the gearbox is identical. These can't be bought new for a williams but can for a 172.

Hi, there are 3 gaitors on the gear linkage, the parts numbers are 7700718856, 7700859626 and 7700104811 all I think are still available, the wishbones for the williams over the clio 2 are different part numbers from renault.

They aren't the same, when people fit the 172 stuff to a williams/valver it brings the wheels out further

 

[16v_paddy]

The mk2 subframe is also different, 182 cup wishbones also look identical but it's tiny differences that are only noticeable if you take lots of detailed & accurate measurements between them that make up the bigger picture

 

[16v_paddy]

172 springs are a direct replacement for Williams springs

Thats probably because of the subframe as per the 172 cup.

The wishbones themselves are identical

 

[rickyquicky]

Just took the balljoint off to check and the bolt holes are in the same place and same spacing test fitted the 172 wishbone into my williams subframe and it fits like a glove. 100% the same.

Interesting for all mk1 owners with possibilities for extra castor etc. Without changing anything else

182 Cup wishbones are the weapon of choice for the extra castor

 

[rickyquicky]

is the 182 anti roll bar fitted in the same way as ph1? If so they should be a direct swap also

 

[Jaff.]

a lot of that stuff is very similar if not the same. megane and 19 have very similar wishbones, hubs are very similar, everything on the front end of those age cars would be easily swapped with not much work i imagine

 

[rickyquicky]

Here I trial fitted the ph1 wishbone to my Williams subframe, measured all the bolt hole distances to the edge of subframe then did the same with the Williams wishbone. All dimensions EXACTLY the same, castor included

I thought this would have been common knowledge by now!?

 

[Coops Mk1]

good work, nice bit of beta that. I'm not mega up on Williams stuff as I just ran all mine around as dailies until I sold them, were never projects so never changed wishbones
all I know is you need the 172 ball joint as well as the Williams item has smaller bolts and bolt holes

What a great thread.
Never knew this, ideas for the future.
