I bought a 1970 Duster 340 back in Oct. I'm still researching what's stock on it and what's not. It's an original 340 automatic car and has a 8 3/4 rear end. It has 14 inch tires on the front and 15 inch tires on the back. Is this stock or has someone likely changed the rearend.
Quite a common upgrade. See if one of the front rims fits the rear. Unless someone upgraded both front and rear you should have the stock 4" bolt pattern.
