87 4 cyl brake question

The firewall is the same, not shure on the booster. I tried to put 90 5.0 front brakes/spindles on my 86 and found out there is about a 1/4 inch difference in the struts. (where the attach to the spindles)the wheel bearings and a few other things are different too. I've hav 3 4cyl 86, 86, 90 and 2 5.0 86, 90. The body is the same on them all. Just make shure you keep track of what you change. It might sound stupid but when it comes time to replace brakes/bearings.... you will want to know what year/ eng/some times they need a vin to get the right part.
