There isn't a throttle body spacer (nor would one have any benefit to us). There is an intake spacer that goes between the upper and lower intake manifolds that currently is not in production, and none are available. However, 99mopar is trying to get a group buy going through the original designer of the third version of the spacer who might be able to get some made. There is a recent thread on this.
Chrome window trim is available used. You can find it at almost any junkyard, though it's tough to find a set in good shape. Keep an eye in your yards, and on the B/S/T section for anyone selling a set.
