I'm pretty sure my Citroen H Van had inboard front discs... it was just the
ID19 drive line turned around!.
Burley Motorsports makes a neat and inexpensive kit to mount A4 rear discs
on a Vanagon.
Dixie's rear discs will NOT be inboard. Anybody who's had to deal with the
inboard rear discs on a Jaguar X-KE will be able to tell you why they
shouldn't be allowed on street cars! ;)
