Here is a technical video of sweeping a 33-34 frame . Trying to get the low and using the spring on top of the axel like it was first built into racer back in 1952/53. My first time doing this . I am sure I made some mistakes along the way but it’s done . Sitting very close to the old photos and videos . This is in my build thread but a friend of mine on here suggested I pull it out snd make its own post Incase anyone searches on the topic . I hope someone can find it useful ......
