>>> Rich mixture ? this one is easy to fix, but you need a exhaust gas
analyzing machine... I have one here in Montreal, if you need it :-). Or
you may just lean the mixture just before the test, hope it will be
enough and crank it up after the test !

Interesting data of the relative power of F-R brakes : 171/280 and
164/268 translate to 60/40 braking ratio. Seems logical, as this is the
weight ratio. What brakes do you have on the car now ?

Don't worry, the problem areas are well known, if expensive sometimes,
but after you'll be done, the car is trouble free. By trouble free, I
mean that I don't need a towing more than once by 3 years, but I do have
some "concerns" each 3 months... and this is my daily driver.

Good luck !
