MX5 NA Questions

Hello Brains trust,

I am working on a concept and I have some questions regarding Mazda MX5 suspension

- Front upper ball joint, the vehicle uses a push in ball joint, is there a ball joint (that fits) that has some adjustment, link this one (https://www.rallydesign.co.uk/product_info.php?products_id=11838) or a bolt in unit, or something similar.

- Control arm weight
I am looking at using the MX5 control arms (front and rear), does anyone know the weight of these components??

- MX5 Steering Column & i shaft spline - does anyone know the details??

- Escort Mk2 steering rack - what is the spline detail?

My thinking is to utilise MX5 suspension components, if people have ideas on arms, mounting, adjustment, etc it would be greatly appreciated.

Thanks

On the standard setup camber (and I believe caster) are altered by turning the cam-like lower inner bolts, which I guess will give you similar adjustment to a top joint as you describe.
I'm not an expert, just happen to have had a front subframe (impulse purchase!) sitting in my garage for longer than I car to remember!

This may be useful to explain in better:

Not sure how heavy the arms themselves are, don't imagine too bad being hollow pressed steel, but the whole subframe assembly is a struggle to move about single handed!

These seem quite reasonable, no mention of weight though...
