today i installed the lower torque box reinforcement plates. i got these off of ebay,they are the Wild Rides Battle Boxes. there are two different models,one that requires cutting the hole for the lower box plate,and the other does not require cutting made for SN95 Mustang's. i'm using the one that requires cutting,as the other one cost more. the upper plates i'll be installing later when i have time to install the 3.73 rear axle. lets get to it. ***TOOLS NEEDED*** 1-paint scraper(to remove sound deadener) 1-scissor or knife(to cut ABS grommet) 1-drill 1-3/8 drill bit 1-9/64 drill bit 1-set stepped drill bits(must go to 3/4) 1-wire brush attachment for drill 2-jack stands 2-car ramps (or 4) 1-jack 1-small file 2-3/8 or 1/2 drive ratchets 1-18mm 3/8 or 1/2 drive deep socket 1-19mm 3/8 or 1/2 drive deep socket 2-3/8 or 1/2 drive extensions 1-9/16 3/8 or 1/2 drive deep socket 1-9/16 3/8 or 1/2 drive standard socket 1-3in cut off wheel(to open hole,already done) INSTALL FOR DRIVER SIDE. -all pics of driver side,unless otherwise noted. prior to install,i painted the plates to prevent rust. as you can see,there is a driver and passanger side,dont mix them up driver side shown. note how it is angled towards the front. 1.place front of car on ramps(or jack stands),and rear on jack stands. 2.with 3in cut off wheel,open holes under car to fit lower plate.(already done) 3.inside car,remove rear seat bottom and move insulation.(my seat was already out) 4.disconnect ABS sensor and push grommet through. 5.under car,move it out of the way.my exhaust was stone cold,so i just threw it over. 6.with the paint scraper,remove the sound deadener.use the top plate as a guide.push the scrappings out the ABS hole. 7.with your drill and wire brush,remove the paint around the top plate for welding later. 8.with your 19mm and 18mm sockets,remove lower control arm nut,and back out control arm bolt just enough to slip the plate over it. 9.tighten the nut to properly position the lower plate. with the 3/8 drill bit,drill the 4 holes,using the lower plate as a guide. *remember to deburr all hole drilled* 10.inside car,center punch the plate and drill a small pilot hole. 11.with your stepped drill bits,open to 3/4 inch. 12.position top plate,insert bolts through. 13.from under car,scratch ABS hole position on to the bottom of the top plate. 14.center punch hole,drill pilot hole and open to 3/4 inch. 15.on ABS connector,file down the tabs just enough to fit through hole. 16.with knife or scissor,cut grommet.(pass side shown) 17.insert through bottom. 18.insert through top plate,and sandwhich between the two. insert the bolts with washers through the holes. 19.with a helper,tighten 9/16 nut and lock washers from under car. 20.reconnect your ABS sensor. 21.repeat steps for passanger side. heres a pic after i finished.(sorry for the dark pic) i did not weld the top plates yet,did'nt have my welder at this garage. and a pic of the SLP's,just because while your under there,its a good idea to look things over. i tightened the h pipe at the headers,looked for leaks or anything else out of the ordinary.
