i called opie up about 4 or 5 years ago. i was about to order a shaft from him, he talked me out of it. told me i was better off taking my money and buying another transmission as a spare. and guess what, he was right. i never poped the stock input on my 2wd truck. it made a lasting impression on me to spread the word, opie's good people. he could have put some cash in his pocket and still had me as a satisifed customer. but he offer up a bunch of free advise and told me to put the money to a better use.
