9" fox body housing

Are the upper control arm mounts raised on after market FoxBody 9"
housings?

I want to keep the factory rear geometry correct. Our car launches
straight with the factory control arm locations, and feel if I convert to a 9" rear that the upper mounts will be raised at the housing and move the lift towards the rear on our car. Am I dreaming or?

Thanks.

What companies have you looked at for the housing?
