Music to my ears!

Did all 8 1/4" rears have threaded adjusters to adjust backlash? I thought they were adjusted using shims. I got my 8 1/4" out of a 73 Dart if it matters. I was planning on sending it out to put the new gears in because I thought it was the shim type and I didn't want to deal with it but if it has threaded adjusters, I can do that myself. Woo-hoo. Please tell me this is true...(but no lying...hehe)
