I am a 1st time builder and would like to thank anyone that has taken the time to help me out in the past. This is a great site.

I've been told that GM pump AN fittings are different than Mustang II AN fittings. I would suppose that the line sizes are compatible when connecting the system together.
Donor vehicle is 91 Astro 4.3 v/6. Stock GM pump and mustang II from TCI "Total Coast Involved"
Wondering if someone who has done this set up can help me in determining line & AN fitting sizes?

The rack will need 5/8" x 18 (return) and 9/16" x 18 (pressure) fittings and they seal with a rubber o-ring not a flat washer like some companies sell.

Thanks again guys. Good info. I have ordered the kit from Jegs. Hopefully when this ride is built I can post some pics.

Hi,you need to replace the GM valve,with one from summit or speedway.in the original valve ,the hole is too big,which,with the mustang 2,makes the steering flaky (for lack of a better term) maybe faster? anyhow this valve slows down the steering input.

We have had much better luck with the o-ring fittings than the banjos. The problem with using a flat washer is the rack body has to be 100% true in order for it to seal. Which 1/2 of the time isn't the case.
