Bongo Fury

Any help appreciated on this!
The metal tab on the end of my ignition barrell has sheared off. So I ordered a new (used) barrel. But the replacement part isnt the same. My existing barrel has three fixing points built into the housing, whereas the replacement one doesnt have these, so cant be fitted.
Do you know how I can get the right replacement part?
Thanks!

Do you have pics ?

Just to follow up my post (hope that's not too bad form), it looks as though I mistakenly ordered the non-airbag model part. The airbag version (which I need) has a long bracket attachment and a couple of other fixing points.....

Easy mistake.

Let's hope you're sorted soon.
