Hey Mark. Its a 6 cylinder car. I would love to put a straight axle under it but i have too much money invested in the front suspension.Its a fatman front clip with mustang 2 suspension. I've had the car a few years had the original suspension under it when i got it. right now going to street it. maybe a straight axle in the future. I have changed my mind (what nind haha) twice on it, but for now a strret rod. Have the front fenders on it now try to send some more pics in a couple of days. The straight 8 cars do have a longer front end. Roy B.
