Anybody install Dynatech SuperMAXX on their early Expy?
I'm thinking about installing headers on 98 5.4 4x4 Expy. I like the Dynatech SuperMAXX setup, however Dynatech only shows part numbers for 99+ (122-842200/122-84210). Any chance anybody has installed one of these on a 98 5.4 4x4 Expy w/o much hassle?
