No it's not a straight axle it's an older style chassis with the pin style wheel mounts I just put the pins in the bottom hole on the front and the top hole on the rear suspenion to give the gasser look. The body was from the Hemi under glass kit with the chassis from the '69 Barracuda (AMT reissue) but if you have any other ?'s or need pic's I'm more than happy to help
