I wish that I had Andrews adjustable pushrods. The other day I was adjusting my Screamin Eagle pushrods and while I was locking the adjusting screw down the nut cracked. I was able to make a new nut up using a 1/2 hex nut and drilling it and tapping it. I don't know if my dealer will be able to get the proper nut for me on time as I am leaving for a little trip this week. The nut that I used is probably just a grade 5 nut, but I don't really think that it should make a difference. If it was an Andrews pushrod I could phone the engineer there and he would most likely send me out a new nut. I might call him for advice anyhow. Who would you call at Screamin Eagle? Do they even have a contact number?
