Steering column is hitting the headers and melting the plastic

You can also shim motor mounts. Almost always need one 1/8", 1/4", or so, to move the engine away from stuff it is hitting on. I used a 1/4" thick "washer" on the left motor mount on my Dart, and it solved every clearance issue I was having. Sometimes it's not quite so easy.

That’s what I said in the post above yours. I made these up over 40 years ago and used them on a couple of cars
