I used a Progressive Automotive crossmember back in the early 80's when I built this all-steel A-bone tudor. Note that I did use the original strut rods. The only modification I made was to fabricate tubular upper-control arms and narrow the installation 1" to fit under the Model A fenders. Back then, this was fairly new technology, and I was concerned with the strength of using both upper AND and lower A-arms. I wasn't 100% thrilled with the look of it, but with full fenders, it really didn't show that much.

This A-bone had a 454 Chevy, Toploader 4-speed and 4:10 gears. I had no trouble running mid to low 12's with it, the geometry aligned perfectly and it ran straight as a die on both the strip and the highway.

All that being said, I wouldn't hesitate to use a Heidt's or Pete and Jake's M-II clone IFS.
