Welcome lugmut, cool site here and cool car you have, and dog. Man it must be nice to have a 71 Cuda, thats what I would like but never found one, or one I could afford! So I'm thankful for my 70 440 4 speed Cuda, someday I'll get to restore her. Lugnut is cool name, and being a 71, I guess you're right hand thread all the way,ha ha!
