....on my way to mustangsunlimited to return my 3:73's and purchase 4:10's instead.....Im convinced!! I was going to get the Mongoose Vortech kit over at MPH next month, but I would be depleting my whole savings account and something tells me thats not to smart, lol. So it's 4:10's, Flowmasters (already have my BBK O/R-X), Pro 5.0 shifter and SCT X-Cal
