Front coil spring

I am replacing the front coils on my 66 skylark, a complete front end rebuild. 300 ci engine, not a GS of coarse. My question is has anyone used a cushion on the front coils? If so which end? They are flat so it looks like for the top of the spring. I know the original ones don't have any. I have a pair of cushions about 1/4 thick, good idea or not? Thanks for your insight.
 
Does your coil mounting funnel the coil to center even if you tried to put it in wrong? I would look at your witness marks and see if you could just smooth out coil rough edges on contact surfaces so that you keep suspension noises to a minimum. Metal to metal will make noise.
 
Thanks for the reply. At the time of this post I had not installed anything. I just wanted to know if anyone had used a thin flat rubber cushion on the top of the spring. I did not use them on my install, do to lack of positive feedback on the question. So they are installed like stock , metal to metal.
 
Adding a small thickness rubber cushion will do little or no harm to anything.

IF THIN ENOUGH will NOT raise the front suspension.

IF anything should keep down metal-metal noises.

Just my thoughts.

When replacing the front coils on your 1966 Skylark, using a 1/4-inch cushion at the top of the spring can be a good idea, especially if you're looking to reduce noise and isolate vibrations. While the originals didn’t come with 685/672B bearings, many restorers use rubber or polyurethane isolators at the top of the coil spring for improved ride quality and to prevent metal-on-metal contact. Make sure the cushion fits snugly and doesn’t interfere with the spring's seating. Also, during a complete front-end rebuild, it's important to inspect and, if needed, replace the front taper roller bearings to ensure smooth operation and avoid premature wear from additional suspension stress.
