I can't really see your engine in your Jeep but it looks kinda like you have the L-Head engine instead of the F-Head engine. If you have the L-Head / Flathead engine then that carb is correct for that engine but neither are correct for your Jeep.
It depends on what you want to do with your Jeep. If it runs fine the way it is and you can enjoy it I say run it awhile and have fun. In the mean time if you want you can chase the correct engine and carb. Alan
