Unhappy How to put a 4 1/2" door jam in a 6 1/2" wall?

Recently purchased a 20 year old house. The man door in the shop is beyond repair. The door jam is the 6 1/2" variety. I haven't been able to find a prehung replacement in that width. How/what can I do to make a prehung door with a 4 1/2 " jam look like anything other than a mistake? This is the first time I have done something like this so I am somewhat clueless particularly when it comes to the terminology.
TIA,
jc

Best thing to do is special order it.

If its a shop door you might consider getting a welded frame steel door... more of a commercial door.

Otherwise you add 2" onto the exterior side of a prehung jamb. But its better to get a wider door from the get-go. It would come with a wider sill / threshold.

Thanks. I was hoping for a quick fix but I guess that is a no go. It took a while to find one, a long while. I ordered it. I should have it by the end of August. Oh well. On the plus side I did find this DIY site. I will be doing a lot of reading here and might even be able to provide a comment or two along the way.
Thanks again for the reply.
