They have a serp. belt arrangement - I'll look at mine, I just so happen to have, so
good idea.
I am able to get the AAN serp belt setup on - It looks beautiful, that is until I try to
drop the radiator in place.  Shame I think it needs to go.

Didn't the VW Eurovan use a serpentine belt arrangement that can adapt to your AAN?

What I was trying to do is utilize the serpintine belt arrangement of the AAN  - I have

the AAN engine in with serpentine belt setup from AAN deleting fan and front radiator.

The stock radiator/condensor interferes, so this option may be out and I may need to

revert to three belt combination. So before I yank the serpentine belt setup, I'm seeing

if other alternatives that can retain the serp. belt. Perhaps there is a custom

raditator and/or condensor or ??  If radiator/condensor were about 1.5" narrower at

bottom, it would work.

Also, I presume that the best three belt setup will be using 3B arrangement, but recall

some fitment issue when I installed MC  in a CGT or can I use the 7A arrangement which

put AC on turbo side( I can't find my old one to even fit check it). 

Engine is using RS2 intake manifold, IA exhaust manifold, RS2 turbo, AAN filter block

arrangement, RS2 core support with integrated crossover pipe.
