[Vwdiesel] 90A diesel alternator?

[Shawn Wright]

I've studied ETKA, but the pics are notorius for inaccurate depiction when 
similar parts are used in different models. They will often show the most 
common variant, and then 3 alternate part #s referencing the same picture. 
It might be there, but I haven't found it yet...
If I understand correctly, all Bosch 90A from around 86 to mid 90s are the 
same for a VWs, so my 90A Vanagon unit is the same as a Jetta one. But it 
still doesn't help me imagine what the mounting might look like... :-)
I'm in no rush, so one day I'll find a 90A installed on a Jetta and study it...
In my case, I need it to work with the PS pump I have, but no AC. According 
to Autozone, they '91 Jetta w/o AC has the 90A unit, but the '90 Jetta has 
the 65A for both A/C and non-A/C...
