Repairing leathers

[Black Cat]

Hi,

Is it possible to replace the zip that joins the jacket to the pants on a set of leathers ?
Does any one know a place that can do this, near Romford if possible.

I've tried a few local places that do alterations but none of them could do it.
I did buy a zip and was going to try myself but realised i dont have a clue what im doing.

Thanks,
Gave them a ring and they can do it. Not too expensive either.
The shop is near Saffron Walden though not Ilford but thats ok .
