18's with 275s on a Duster

The 18’s were for a different project so the sizes I have are just what I’m dealing with. It would would have been great if the fronts fit but I really didn’t have high hopes. I guess that’s the beauty of three piece wheels though. When I figure out what I need for offset I can contact Forgeline for some hoops.

The lengths I’m willing to go on this semi-freshly painted car is:
Roll fenders, lengthen fender support rods, and cut the pie cut like @Craig Burriss . I have touch up paint to airbrush over the weld.
In the rear, I have an an 8.25 now but also have a 68-70 8.75 housing w/ a 489 core.
A previous owner had put an MP leaf spring relocation on it and reverse tubbed it. The man I bought the car from had the reverse tubs “fixed”. In regards to the springs. I could easily swap back.

I would need to get rid of my $1600 Accurate Ltd. OEM exhaust system but I already have the TTi’s that was for the other project. Selling the exh. system and 340 manifolds could buy my first set of tires!

I have 90% of the parts on hand to do this. I need a driveshaft, a rear-end build (?), wheelwright, heat gun, and a roller.


I measured with the wheel face up, from the ground to the wheel mounting surface. Is this the correct method for a b.s. measurement?

Is this for your '73?
