There is an AE86 version which has a shorter pinion. I know AE86 is compatible with the AW11 but I dont know about going backwards putting the longer pinion AW11 version on an AE86..
Are you sure you are getting the AW11 version of this rack? The AE86 version is more plentiful, and its possible you are actually getting that version.
Does he know the model number? Or the length of the pinion? If the shaft is about double the length of the pinion gears, its the AE86 version, if its over double (almost triple the length) then its the AW11 version.
You might research the backwards compatibility of the AW11 version to the AE86 application if you are going AE86 later.
There are some install threads and discussion around it from previous group buys on MR2OC.COM if you dont find info anywhere else.
