Danno,
Your early ZF with the single rear mount can easily be upgraded to an aftermarket dual sidemount system. I know Dennis Quella at Pantera Performance Center (Denver) has a great SS unit that uses the stock side mount holes on your ZF and the rear sway bar anchor points. Call 303-660-9897. Go to the following to see what they look like.
