I've just begun to build a 37 plymouth coupe. I plan to use a MII front end. My frame rails have a large hump over the the axle area. I can't understand how the crossmember would attach to the rails since they seem so high. On the phone Fatman said I do not need a frame stub but a year and a half ago they said I did need stub. looking for anyone who has some experience with this setup. Also I'll be using a GM 350 so I also need to consider motor mount position. Thanks
