disk brake conversion Q's
Concerning the safety & smaller lower ball joints - most feel that the safety gained is due to the larger attaching bolts between the lower ball joint arm and the spindle. I forget the size difference, but it is much stronger.
I am converting mine right now to the 73-76 and I can't wait to have good brakes instead of the "every stop is a panic stop" 9" drums.
Good luck tensec340.
