'90 Audi 80, '87 5kTQ, '84 5kS Timing Belts

[Michael Spiers <mikes@specnet.com>]

Does anyone know if the AST 2079 and the AST 2084 harmonic balancer tools for
the 5000's are the same tools needed for a '90 Audi 80?  I'm assuming so, but
figured I'd ask!  Also, is the timing belt proceedure for the 80's the same (or
reasonably close) to the proceedure for the 5000's?  My sisters Audi 80 is
about to turn 60,000 miles and needs a timing belt, I'm thinking of telling her
I'll do it for her if she'll split the cost of purchasing the required tools
with me!  TIA.
