Default 1973-15" rim backspace ?

Hello;
I hope you guys are not tired of this one. I would like to jump up from 14 to 15" rims on my 73 convert. I have seen the famous chart with the 275-60-15 with a backspace of 4.5 to 5.5 My search has only come up with a standard backspace of 4" I have been looking at the Cragar line. I want something in a steel chrome wheel. Is this a high dollar custom rim? Also what size of larger 15" rims and tires is everyone running? Thanks Dave

If you're looking for chromed steel wheels and correct backspace, how about 15x7 Magnum 500?

Very nice car. I like that look, but will need at least an 8' rim for the 275-60-15s
I think I'm bent on getting that size.

Ok, I have the back rims and tires on. I went with Cragar soft eight in a 15' rim with a 4.75 backspace (they came as a stock rims), and 275-60-15 BFG's.
Now, What size would look best in the front. Back to the chart it looks to be something around 225-60-15?--205-60-15? I want the front to drop a little. Right now the back is just above level. Thanks again Dave
