Mine are curved to clear the armests in my '63. They were done by a local chassis shop and, while they aren't 100% legal to the letter of the NHRA rulebook, I've never had a tech have an issue with them. We race at 5 different NHRA AND IHRA tracks with it.
I like them welded in vs. the swing out style because of the added rigidity to the chassis.
I also did not go with swingout because I wanted the bar to help stiffen the car. And I dont have a curved bar as its straight and I can slide over it real easy. But I did have to remove my armrest. Ron
