id try the 68-72 nova -same as 67-69 camaro

You can switch to the metric rotors and reduce the width and inch on each side. It requires another wheel bearing and a different caliper but it is not expensive especially if you are rebuilding the front end as part of the project.

The Trans-Ams produced for the Japanese market in the seventies, when we started to kill their domestic auto industry with our cheap, high quality imports. After gas got so ridiculously cheap in the early seventies, people all over the planet wanted big, honkin' American V8s. The Super Duty 455 outsold every four-cylinder model in Japan that year... http://www.jalopyjournal.com/ubbthreads/images/graemlins/laugh.gif

'78 to '87 (or something close to that) Monte Carlos and the other GM cars based on the same platform are called Metric because fasteners and measurements are metric.

The metric front suspension is narrower than your Trans Am front suspension. I think the track width is 58.5, but that's from memory and could be wrong... I think the suggestion is that rotors and calipers from the Metric frame will swap to your subframe and result is a narrower track width.

However, I know what a Metric frame is, I don't know the details of what will swap where, and give what result.

monte carlo is 58.5" track
camaro is 61.3" track

hope it helps----ray
