Swapped st with rear mount troubles Options

[supra12big]

Hi, I have been trying to this mount for a couple hours now, heres the story its a 94 celica st with a gen 2 3sgte in it, the mount that was on there at first was the st's orginal one with a modifed bracket, so i went out and bought a alltrac rear mount and bracket, the bracket fit, but when i put the mount on, the hole where the screw goes through was not even close to the bracket, so everyone was telling me to get a st205 rear mount and bracket, are the brackets the same, and could someone get a pic of a st205 mount, and would it allow for it to work, thanks, need help don't have a car untill finshed
