Capri/Escort strut help

[v8ian]

Not up to much theses days, covid seems to have sorted that, But, Im still thinking projects thru, Im sure somebody on here will know, Im making for a friend a pair of A arms to fit a trackday car, the choice has been made to use A arms to hold the strut in place, this will give him a better way to mount the ARB of his choice where it suits him, So.......... my question is does anybody know of a bolt on type of ball joint that has the same taper as the capri/escort TCA, I think Austin Ambassador do fit the strut, but are push fit into a hole, I have seen these come adrift before. so, do I have any other potions???

how about cortina mk3 etc ? or are they all metric ?

If you're making the arms, can you make them with a rose joint then use tapered pins for the ball joint?

Many years ago on the twin turbo MkI Capri we built, we used some Opel Astra ball joints for the A-arms we built. ISTR that they should be a match according to catalogues but I also have a memory of them not matching the taper 100%.

My notes not say the Capri/Escort has a 1/8 taper and a cone diameter of 13,2 mm, Astra is 13,4 (top of taper) but the taper is listed at 1/6 by the Sidem catalogue. There are many joints with 1/8 taper but most are thicker. Not sure if drilling out the top to 14-15 mm is feasible, but that would open up a number of options.
