1970 Dart rear wheel size and offset for stock eliminator

[jinxy]

I'm considering making my '70 Dart a stocker. I would like to get a radial stocker tire under it. I realize I'll have to have the front of the wheel opening enlarged an inch and 1/2 or so.

Anyone run a Dart in stock? What size wheel and offset do you use? Which tire and size? Can you use the offset spring hangers that mount in the stock location?

I'm new to the board, but I've bracket raced for a number of years.

Any input would be great.

Thanks

Jeff
