I have installed new Door and Door Jams inside a Duplex but the Jams weren't as wide as the old ones so now there is a 3/8 space on the outside (interior Door) of the jam and one that 1/4 on the inside of the Jam.  Any Suggestions on how to fix this.  I don't want to have new Jams Made Cuz I don't have much time I only have  two more days to complete this Job and I still have alot to do other then these doors. Any Help is appriciated!

Thanks.

either cut spacers and attach them to your jams (aka extension jams)....
or the right way is to make fresh new jams with your added measurement. Its not that hard to make new jams from scratch. Copy your stock measuements to your new larger jam this way your hinge holes will line up. "Make the time.....or you'll be back!"
I use Pine or whatever the door material is made out of. Paint hides everything including making getto extension jams but omly if you sand down any lips in the joint afterwards. It's best to just rip it out and go new again!
