You would think that Koni would be making MII shocks for the front with all of the aftermarket uses these days. I bought some rears years ago, and thought I would find fronts eventually...
Koni does have a rebuilding service, so if you could find some used you would be in business.
Otherwise keep checking eBay.
I bought a set of KYB GR2 shocks for my MII, but have not installed them yet. They should be better shocks for performance driving than garden variety Monroe's, but they won't be the equal of a set of adjustable Koni's. In fact KYB also makes a even higher performance front shock the Gas A Just. Mustangs Unlimited carries all of these.
Speedway Motors carries AFCO shocks for mini stock racing, so they should be valved a bit harder than factory shocks also.
