Hot Rods wheel question

Hi folks.
I have found a cool 33 built in the 60 ' s. With it came 3 nice chrome reverse rims the back space is 3.5 inches on a 6 inch wheel. I gave searched for a 4th. I have found a matching 6 inch but the backspace is only 3 inches. Will it work or am I asking for a pile of Problems? Thanks in advance.

 

i don't think you'll have much of a problem, I've done the same before. its more of a question of; will it look odd. sometimes stuff like this will drive you nuts.
