i want to buy a front disc brake kit to go on my 1948 ford axle but also want to run traditional cowl steering. i was looking at a few speedway offered but it says wont work with bolt on steering arms...are they considering that to be the lower arm on the spindle that you can bolt on or the actual hoop style arm i will be using for cowl steering? i will be using my original spindles with 15" wheels. anyone have any recommendations?
