ok dave . the airbags on these things is to be polite , at best problematic . ford air ride systems are JUNK . the track width is the same as my 53 which i want to say is like 60 inches . the hub bolt pattern is 5x 4.25 . easily remedied by a: buying mustang cobra irs hubs / 99 up cobras for 150 a peice or redrill the hubs for 5 x 4.5 which is what just about every ford and gm car uses since the creation of dirt . it is an aluminum case a very nice sought after part , and since it's a v-8 it is 8.8 based . the a arms are aluminum , the uprights / spindle knuckles ? are aluminum on all the irs rears . any 8.8 28 spline track lock will fit , summit sells one from ford motorsports for 195 . any 8.8 ring and pinion fits also . cobra parts are all 31 spline and heavier duty halfshafts . the 28 spline is being used by some guys i know in our 3650 pound birds making 600 horse without any issues with an automatic . try tccoa a thunderbird forum / mn 12 platform forum im on for any info , but not very freindly towards other makes . pretty much ford only . as i said before these are a bolt in in any frame rail 34 inches in width like my 53 , except you have to pie cut the front mounts and move them in to the proper width so i'd say they could fit a whole hell of a lot of other makes and models easily . i know they are becoming quite popular with the 50's era ford passenger car croweds for an irs . they are readily available , you can get poly bushings etc, from supercoupe performance , summit , jegs , and energy suspension , many times outside of supercoupe you have to look under mustang cobra 99 up as they use the identical suspension , just wider . if you want air bags go aftermarket , or just buy a set of oe bird , mark 8 , cougar springs and shocks . the supercoupe and xr7 and the sport modls had the best rear springs as far as rates go . as you all know i had a 91 just given to me , free with an 5.0 and my 4.6 was a 200 car im still beating the hell out of so they are CHEAPLY had !!!!!!!! later .
