Can I narrow A body 8 3/4 housing 3"?

Thanks for the input, I did order new ends before I posted this.

I don't see how anyone would want to use this housing as it is, if it were to remain at the stock length, the tubes would need to be cut down and replaced, so why not shorten it?
I'm not concerned about making a few bucks, I will have over $1,600 into this rear in parts by the time it is done.

Thanks,
Steve
