I have been making a list of things to do. and a new suspention kit was one of them. and i looked a jegs and they have a coil over spring kit that is fully adjustable for mavericks and comets http://www.jegs.com/webapp/wcs/stores/servlet/CategoryDisplay?lang=-1&catalogId=10002&storeId=10001&categoryId=74652 I thought this was pretty cool considering that this is better that making your own from mustang front end. I dont know if these are the same as the MustangII tho.
that is designed to use the stock shock towers and such. not the same as a mustang 2 setup, but great for a cornering car.
You can buy a MII and get rid of the shock towers, get disc brakes, and add rack & pinion steering for the same price or less.
total control products deals in early ford suspensions such as mstang II,coil overs, disc brakes and a whole lotta other stuff. you might wanna try them out
