As a complete rebuild I would recap everything on the car metric. Nowadays they are far more readily available and also if the car was ever sold on in years to come it would be better for the new owner.
Hi Manu, measure O/D of bolt, and use thread gauges to ascertain pitch. I reckon it will me metric coarse. 1969 Sarlouis Germany. Metric has 3 categories Coarse, fine, and special pitches. Repair with a nutsert, sometimes called a clinch nut, or Advel nut, or hank bush. Wedge shape is to allow for the displacement of the leaf spring, as you move one end through an arc the angle will change, this shape is to compensate.
Hi Mano. I agree with previous comments... threads should all be metric but you might find that processes like media blasting, on top of a certain degree of corrosion, have fouled the existing threads and a thread chaser might clean them up. You might find it's the thread pitch that's different to what's common these days, maybe 1.0 or 1.25 rather than 1.5. I have an idea that lowering blocks with asymmetrical surfaces are to correct the differential pinion angle when lowering. Loving the content and best of luck!
Probably AF is if it is not Metric. Ford used AF in the UK at least, until going all Metric, but some fixings took a bit longer to change over to Metric.
@@Classiccarbscouk Yes that is right, all 60s fords in the UK used AF but as the Capri was to be a euro car it was probably the first to go Metric..however there may be a few obscure bolts (like your roll bar) that can be either. .or something else but definitely not a British thread like Witworth. if it is AF then something like a 1/2 AF... 9/16 AF ....or even 5/8 AF socket should fit it.Most likely to be a 9/16 AF by the look of it.
My dad's 1971 German built ford Granada was all metric. No one has used whitworth since the 50s. You need to both measure the outside diameter and The thread pitch with a set of thread pitch guages, you get them through all thread types you might as well buy a set. Then when you have identified exactly what the thread pitch is, the thread guide will also tell you thread type, and an engineering chart will tell you the outer diameter of finished bolts
@@Classiccarbscouk what I meant to say thread pitch gauge also show you the profile of the thread. So you first identify the type of thread and the pitch then measure the diameter. Cars often use threads that are not iso standard..odd pitches compared to diameter. But if you identify what you need someone with a lathe can make it
If I remember right Mark 1 Escorts were imperial and Mk2 Escorts were Metric. At this time Fords were coming through with a mixture on the same car because of the changeover. I would expect your bolt on the Mk1 Capri to be imperial and Whitworth if bolting into the bodywork.. Maybe the slopes on the blocks are an effort to align the axle to the gearbox.
@@Classiccarbscouk Good evening Mano, I've checked and the bolts that hold the corner bracket to the body are 3/8 24 (UNF) and 1 inch long, the bolts that hold the bracket for the antiroll bar are 5/16 18 (UNC) and 7/8inch long. Hope I can help you with this.
@@Classiccarbscouk I have most of the bolts sorted out, they're a mix of metric, UNC and UNF. So if you have more unknown bolts you can always ask me 😉
Most probably imperial measurements
the angled lowering blocks are to correct the angle of the rear axle when the car is lowered hence aligning the prop shaft correctly with the axle
Drill it out and tap it to what size you want
Might have to be the case... thanks Pete 👍

It's all coming together for Kate think it's metric I could be wrong but am sure you will get it bud.👍

Is that 'AF' meaning american fine?

I don’t think the Germans ever used Whitworth did they ??🤔(always metric)..
Best of luck Mano finding the right thread pitch, sadly i have no idea either.
Thank you Ian 😊

Will ha e a look at metric again, thank you 👍

Spot on buddy, thank you!
What about taking a bolt from a donor car and using a thread gauge?
I ve done that Bill. The gauges don't fit it too well. I will try AF though, incase it's american fine
@@Classiccarbscouk I'm sure you'll sort it.
I would have said metric. But you have a capri outside I thought what is the bolts in that can you use them 😮
Yo dude just rang My mate he had the same problem for a Corsair he solved it by getting Imperial nuts and bolts from America 🤙
It could be american fine
a/f
Dudes!
Dude!!
Dunno Mano ..got any easier questions ?
No, MK1 Capri's were certainly not all metric! This will be UNF or UNC. I'll check this evening for you.
If I check in my order history this probably will be 5/16 x18 (UNC).
Well, I've ordered a Whitworth tap & die set.
Seems to be the match with 24 3/16 gauge

@@wimcomeyne7775 This helps a lot THANK YOU Wim!!! :)

Pretty sure they are a metric course thread you may be trying to use a metric fine thread hope this helps.
I've already got the bolts. None of my thread gauges fit them well.
Mano dropped you a link on the facebook page bro.
Got it! Thanks Ian 👍
@@Classiccarbscouk Hope that works out for you.
My friend has a 1969 ford Capri I'll ask him for you 👍
My friend said his Capri is metric 👍
Thank you buddy 👍
No worries 👍
