1968 roadrunner question on rear setup

[nazar]

cool beans, definetly keep me updated on the progress

I will be making my own subframe conectors, going to do something different looking, perhaps X them instead of just parrallel

Offset of the wheels will play a big role in the front to get it to fit and unfortunately there is no prior tests of it so I am not sure how to go about picking the right wheel to fit a 275 up front

THe rear i want a 335 so I think I will mini tub it, shouldnt be too bad, just shorten the rear end a bit.

What is the advantage/disadvantage of a 3 link vs a 4 link?

Let me know, I will definetly be ordering one.

As far as the front, i wouldnt mind a clean kit that keeps the stock frame for now, i dont want to spend too much money on a whole new front k member setup

Post some pics of your 68 you guys are working on

The stock rear end was either a mopar 8.5 or a dana 60. I know for a fact that you can fit 15x11 inch wheels in the back without tubbing, but that doesn't really help you all that much.

really? I heard guys barely fitting 275s on 9" wheels, so how will an 11" fit?

I just read up the specs on the hammer. It says the rear has a mopar spring relocation kit but doesnt mention anything about a narrowed rear end, maybe just moving the leafs is enough? I cant imagine that, especially since they used a 19x13"

I need a way to find out the wheel specs(offset and backspacing) on that hammer car, supposedly they didnt narrow the rear end and have a 13" wide wheel on there

I think offset and backspacing is key because the mopar leaf relocator moves the leafs in 3" on each side, that should clear up alot of space, and I can always cut the wheel well out and modify it...if I dont have to shorten the rear end, I dont want to...I'd love to stick a 18x12 back there on a thick tire, the car is so long and big that it needs a big tire to somewhat put it back in scale

Ok mine are 275/60R15's on 9 inch rims with a few inches(3.5 fingers, very scientific) to spare, but now that I think about it the trunk has been replaced and I'm the 3rd or 4th owner doh . It probably has had a little more work done to it than I knew about.

i think with a custom wheel i can get any backspacing i want, as long as i can create clearence inside the car, lol....so i dont have to cut the axle down....just pick the right offset and backspacing, probably will need about 6.5" of backspacing or so...I really want that wide 12" wheel look with a wide tire cause its such a huge car

I am thinking now of the CCW classics, 17x12 out back, 17x9 out front

Ok guys, just found out it has the 8 3/4" rear end swapped over from the hemi and also has power drums all around

The rear end I am excited about, too bad parts for it are pricey, and its gonna need a diff to get both tires to lock

But at least its beefy

Hemi Roadrunners came standard with a Dana 60. The standard rear in a 68 RR would be an 8 3/4.
An 18x10 wheel with 295/40 tire will fit easily on the rear. That extra 1.5" of tire width (295 vs 335) is gonna cost a bunch.

are you assuming htat 18x10 fit with the leaf spring relocator? Because im goin to get the mopar 3" leaf relocator? or are you talking about the inner fender? I was lookin at it, seems prety hard and thick if i had to cut it, but seems like theres tons of space if u move the leafs in more

I was hoping for at least a 11-12" wheel. I will get the wheels built in a way that totally maximizes offset and backspacing so it comes right out to the fender and goes all the way in as far as possible inside

The car also has power booster drum brakes all around and the upgraded sway bar option from the factory

Needs new interior, windows, paint, some exterior bits, not bad for the deal i got, the engine has been rebuilt and is very fresh with a denominator manifold, big cam and rebuilt carb, but needs fuel lines cause 1 is leaking i think

I just bought a '70 Barracuda, which si the first Mopar for me too, so I'm in the same boat as you. I have no idea what the "tried and true" info is about backspacing and rim/tire size etc etc.

When I did my '69 Camaro, there was gobs and gobs of info about what backspacing and rim/tire size would fit a 1st gen. It was easy to find out. This car is going to be a bit trickier to make sure I get stuff that will work.

the wheel deal is quiet simple

You can do all the measurements on the car to get the exact offset and backspacing you can do

Most upper scale wheel manufacturers offer detailed instructions on how to do so and get the exact wheel to look just like you want

I pretty much want to maximize all the space in the fender, from the outside to the inside fender, as much as i can and as wide as i can, because its a huge car and it needs wide tires to even it all out
