I'm using Energy Suspension urethane engine mounts on my '68 and they work great. '67-'69 all have the same dimensions as far as bolting up. The '69 factory engine mount was changed physically, but the bolt pattern and frame mounts are the same on all 3 years. The Nova shared the same subframe as the Camaro...they are virtually identical and it all interchanges. The only reason a stock Camaro would need the holddown cable is if the engine mount had rotted away. The cables were a CYA item from GM...useless, but they made a good PR program. And they do look nice on a resto! Sweet pic, John Z.
