Still trying to piece together exactly which donor parts my car contains.

andyd kindly pointed me in the direction of a picture of his Cortina axle. Mine, however, looks a bit different.
I asume it is, therefore, an Escort Mk. 2 axle but if anyone can confirm or deny from this picture:

I would be eternally grateful.

its either escort or capri

Yep, looks like an escort to me.

Yeap have to agree with Chris on that, looks like a Escort timken axle. It's not a capri thats for sure, not a late one anyway.

One way to find out is to measure the width.
