This is a weld on bracket kit for your Ford 8.8 axle.  If you have the skills and already have a Ford 8.8 rear end, this kit is all you need to mount the rear end into your SA or FB RX7.  You will need to upgrade to a panhard bar, or create your own watts link bracket.
NOTE: Please specify your axle tube diameter, most Explorer are 3.25" and most Mustang are 3"
 
The kit includes:
Suspension link/shock brackets
Spring Buckets
Sway Bar Bracket
