Why did I put Power steering in my BB A-body

It was leaking from the top seal where the shaft hooks to the coupler. I just yanked out the whole unit and put in a new one. What a pain in the rear. But while I was at it i tidied up the engine bay and under side of the car. Cruze ins are coming! Thanks for the input I think I might wrap that header it is severly close to the box and heat is probably caused the seal to leak.
