Can anyone help with some photos or ideas on how to do this on a 1968 Dart ? I want to give myself more room for bigger tires ! Any help would be great ! Thanks John

What suspension and wheel wells (Stock?)do you have now, and how big of a tire and what suspension do you want?

I think big time did his wheel wells. But he isn't here any more try Josh's board.

Easy raise it in the rear, cut the outer wheel wells likethe ss darts.
Now you can have as big of a tire as you want.

There may be other solutions,,,,,,,,,, what are your goals? Better 60 ft? More consistent? Sometimes the tire is plenty big, it just needs some suspension upgrades. A full run down of your combo would help a lot. Motor, driveline, tires, suspension, best 60 ft, best et, average variance in 60 ft over a day.

The car is a work in progress right now ! It's got full cage 7.50 cert. Ladder bars, coil overs tubs are after market alum Dana 2" shorter than stock each side 3.73 gears ! Motor is in the build process right now but it's 4.50 bore 4.50 stroke alum block gen 2 hemi with F-2 procharger, th400 trans, glass front end, glass deck lid, stock doors but lightened as much as I could with out bending when leaned on ! Got factory back seat stock passenger seat, kirkey drivers ! Aftermarket race car steering column ! It's going to be 10.5 tire car but want the ability to go bigger tire if I should want to ! I'm hoping to have the car done for Norwalk if all goes right !

Oh I don't want to cut the wheel wells like the super stockers ! I just don't care for the look.

there are three choices with the Mopar type front spring box location kit, centered in the rear sub frame like the Mopar chassis book shows, the other two are leaving one side or the other of the sub frame and mounting one side of the box agianst that I've done it all three ways in different cars My current 1969 dart has the box mounted against the inner sub frame rail so the leaf springs will clear the stock gas tank, I did have to massage the passenger side of the gas tank to clear the leaf springs If your running a fuel cell mount the box against the outer sub frame rail and use(weld) a full length strap from the inner edge angled to the sub frame on a 45 degree angle I used the stock rear spring hangars and had them welded into the rear sub frame by Ving the rear sub frame and pointing the hangers straight up . I did have them moved forward so the stock hangers where pointed at a 30 degree angle from the rear spring eye to the moved hanger IHTHs, I would take some pictures but the car is put up for now and not easy to take the picture of the front box

I would get a pair of rear rails from a clean donor car or new rails and weld them inboard of your existing ones, then drill out the spot welds of the old ones to remove them.

Problem with moving frame is my frame connectors and the cage is built off of them ! It's all done so I don't want to cut it out and start again !

You'll need ladder bars and fabricated wheel tubs to notch the frame rail. It made the difference on this car to run 29 13.5 Hoosiers.

Yep that's what I'm looking for. Already running ladder bars with aftermarket tubs ! You got anymore photos of that ? Thanks John

Off the shock mount I have smaller 1 1/4 bars at an angle to the frame also ! I most likely over did it but it's just weight ! And it's in a good place over the axle !

How much of a bigger tire would you like to go in the future? I had 29x13.5 Hoosier QTP under my Dartsport with rails in stock location and unmodified. I think the Dana housing was cut to was 52.5 and I had 15x10x6.5BS weld wheels on it.

Yes but the dart sport is a duster type body right ? This is a 68 Dart, and I really don't want to cut the wheel wells like the SS cars ! Just don't care for that look ! But I think even without the frame notched I could get a 13.5 in there ! It would be really close, but I think it would fit. !

ahh, yea, oops, missed the 68 Dart part. Just thinking of your Duster.

572 with a blower? No question in my mind, you need all the tire you can stuff under it, and THAT won't be enough. Do it right, and do what it takes to put the absolute biggest tire you are willing to run under it. Traction will be poor no matter what, except MAYBE on a prepped track.
