I'm also going to be buying a 3" drop axle from Sid in January.
Abt 8 years ago i bought a 4" drop axle from Mor-Drop in Oakland,Ca. I'm very happy with it but.........it took a long time to get it done,and very hard to get ahold of the Mor-Drop guy on the phone. Its understandable,,,he's been doing these things since the '50s and hes probably ready to retire. Last time i talked to him, he had waaaay too much going on, and no time to do it. He's a genuine old blacksmith though!! His shop is unbelievable.
Ive shopped around,,,and Sid is the man if you want a top quality axle done NOW.
