I currently have a gearbox
It's a Borg Warner box
Gearstick has 4 bolt fitting to top
Was told it was from a Cosworth ,can anyone help me identify it some way please ?????

It sounds like a Borg Warner T5 from a RWD sierra or sapphire cosworth

That should be the one.

There's a pic of a T5 on my website in the gearboxes section.
