Zippy zips for zip together pants?

[Hiflyer]

I'm looking for some new pants to zip with my Alpinestars Jacket,
I have the same pants that came in the set, but will any alpinestars pants zip to my jacket? Or would I need to change the zip on 'em?

If I'd need to change the zip how much would that cost?

I could do a change of zip for about $50 plus postage.
Biggest problem you will find is the ends of the zips on your new strides not being in the right place for your jacket. so a bit of fiddling around to be done, not an insurmountable problem tho.

cheers
