73 Duster Mini Tubbed - How big a wheel?

[68GTconvert]

73 Duster Mini Tubbed springs moved to the rails - what size torque thrusts should I get in the back? It has Mickey Thompson 29x12.50x15 right now with stock a body with 8 3/4. Anyone know backspacing and rim size and width maybe in a 17" torque thrust? I know this is a shot in the dark. Thanks.

Sorry I can't help you, but I mini-tubbed my 70 Dart and I can fit a 15x10 with 3.75" backspace with a 295/50/15 tire AND a 17x11 with a 4.25" backspace with a 315/35/17. I have a narrowed dana with a length of 49 5/8" flange to flange. But I think with a stock length A-body rear and a minitub, people are using a 7 inch backspace...

17x12, 335/35/17 will fit. That's if the rails are the first interference point or at least even with the springs. Measuring for the rear BS is easy and I wouldn't take anybodies numbers without measuring first

In a 17" that's about as big of a tire they make. I have a 345 in the rear of my demon which fits with a slightly trimmed quarter lip (19x12)

Thanks I was kind of hoping for you to comment. Cool I will get backspacing measured for sure. Where did you custom order your rims? I like the look of those.
