[Vwdiesel] ETKA help (!) - clarification

[rbp at 4u2bu.org]

sorry, forgot to say:
this is a '93 Eurovan DIESEL AAB-type 5-cyl n/a engine
looking for specs for idler roller bolt (stud?) and lower timing belt cover main
bolt (is also upper pivot bolt for the water pump)
thanks to anyone who can tell me

note:
there is no stud in idler roller now
I never removed it on disassembly, especially if it is a stud
idler's been rolling w/o bolt, don't know for how long (certainly longer than
I've owned vehicle
what do you think of that ??
