Make sure you do all new steering parts, too. The performance will be directly related to the tires. With tall, skinny tires (stock), it will be decent. With low profile, wide, sticky tires, it will be absolutely eye opening. My 65 is stock, and I like to cruise. However, my 95 is lowered, has custom arms, Bilstein shocks, big sway bars, and 18x8.5/18x10 wheels with sticky 275 40 18/295 35 18s. It sees duty on the street, but has been on drag strips, autocross, and road course.
Two doors, four doors, wagons, and ragtops.
