These roll-bar hoops come prefab and made to order for installing in a 914 application. The hoops can be ordered directly from Autopower Industries, 3424 Pickett Street, San Diego, CA 92110. Ask for Rick (619) 297-3300, here is the website http://www.autopowerindustries.com

This is how they usually come https://pbase.com/9146gt/image/90474060 not exactly a perfect fit https://pbase.com/9146gt/image/90474067 but a great and inexpensive start. By the way, aside from the prefab rollbar hoop, you will need to also order an extra 10 feet of 1 ½ inch tubing https://pbase.com/9146gt/image/90474063 to complete the straight section reinforcement tubes.
