Quick Ratio vs Standard Pitman and Idler Arms

I'm in the middle of shoe-horning a 392 hemi into my 69 Barracuda and the new TTI headers look great, but my idler arm comes within 1/8" of the headers during travel.

I have manual, "quick ratio", steering with a 16:1 box. I recently replaced the steering box with one from P-S-T.com to tighten up the steering. It has a 1 1/8" sector shaft.

I have been told the non-quick ratio idler and pitman arms are shorter than quick ratio, but ordered them and they matched my current set (which I thought were quick ratio).

The part numbers I tried were:
- Pitman Arm - Dorman PA7074PR
- Idler Arm - Moog K7042

Does anyone know if these are the quick-ratio arms?
- Are there different sizes, or is it just in the steering box?

Does anyone happen to have a part number for the shorter arms?

I appreciate any help!
