That post was from Ben Howell. I'm not sure if he is on the list anymore
(I've been unsuccessful at reaching him lately) so I'll take the liberty of
reposting it with my own comments. Read carefully!!!

Ooops, here is a MAJOR problem. The struts from an Audi 80/90 have 75mm OD
bearings and the struts for the 4kq use 68 OD mm bearings (ID are approx. 42
and 39 mm respectively). This means your 4kq hubs won't work. This also
means the 80/90 hubs won't work because not only are the axel spines
different, but the 80/90 uses a bolt rather than a nut on the axel.  Now if
you are very clever you might realize the rear bearings on a 4kq are 75 mm
and you might think you could use a set of those up front....Wrong. The
front and rear axels on a 4kq are different and also have different splines.
You can go a couple of steps further and solve this problem. Get the front
hubs, 4 of them, from a 5000 t or tq and an extra set of 4kq rear axles
(they need to be shortened slightly with these struts) and convert to a 5
bolt system. you can then use the front rotors from the same car you got the
G60's (even the hat size is correct) and drill you rear rotors to work with
5 bolts.

Or, you could fabricate brackets.... or talk to Gary Kaklikian,
<Gary.Kaklikian@Compaq.com> RevSport converted his car to the G60.
