Measure the column you intend to use, think about mounting points at both the top at the dash underside and also the base where it goes through the ca. In the inside of the dash the speedo and quad gauge get a little close for bolt clearance.
I just got a flaming river 30" that fits well. Check the website to see how the measurements are taken. You need to get all the knuckels/U-joints to the steering box you intend to use.
Good luck
