Hey guys.

I've just swapped the brake booster over for the XR6 one.

Now it won't fit to the master, so I did a search and found that I need a black spacer.
Now the XR6 is gone so there's no chance in getting it off which is a pain.

Can I run it without the spacer (temporarily)safely?

Thanks.

you will find you have a leak in between the booster and the master cylinder

I'll throw the gli one back on until I get the spacer.

What type of leak do you mean? I won't have to bleed the system or anything will I?
