Need help with 73 duster's Starter

A guy paid me $120 to put his starter in a 68 Camaro. He reported he had a nightmare of a time getting it out and was not even interested in thinking about trying to get one back in there. I went there looked at it so can you turn the steering wheel all the way to the right? I slipped it right on there no problem. LOL needless to say he was not happy but he was happy LOL..
