On my car, the amount that weight distribution was changed by the wheelbase change, was quadrupled in a positive direction by simply moving the battery to the trunk.

Thanks for the info. 72 Scamp, installing 405 h.p. 360 Magnum, A518, 323 sure grip, just wanting to get all the tire under it I can.
Quick and dirty calculations on my car shows i lost about 12 lbs on the rear wheels from the axle relocation, about .85%. Removing 40 lbs from the front, adding 60 to the rear, i figure compensated. And so did the difference in tire contact patch, from 26" tall tire to 29.
And besides, it just looks so much better.
Do you really think traction will be much worse at 117" than 116"?
12 pounds is a lot of you're on the ragged edge. The last think I would want would be to LOSE weight over the rear axle. It's not up for debate at my house. My house, my rules and I don't like pushin the axle back. You have at it. lol
Agreed I put in a 14x32 slick on my 68 dart. Had to back halve the car and take 3 inches from the front of the wheel well. The body work was done nicely and I rebuilt a new inner fender lip. If I did not tell anyone they were cut, you cannot tell.If I just HAD to have "that" big a tire, I would reshape the front of the wheel well before I moved the springs.

Denny, I freaked when I saw your car at the Nats the first time. Those ghost stripes are over the top!Moved the rear opening forward 3"....the front opening forward 2". Those fender stretchers make the job easy.
Besides better bite by moving the differential forward 1-1/2" you also get the extra room for coil overs and the OEM fuel tank and the fill tube still fits / works.
On the front, when the K / front suspension (I know a guy) was fabricated, the axle centerline somehow got relocated forward 1"

The only reason I would ever do that was if the rear axle was crooked side to side.....and then I'd look for the difference to be in a frame rail or the unibody of the car before I even considered moving the spring brackets. I've just never thought it was a good idea. Beside the bad rear shackle angle, it will also pull the drive shaft out of the transmission tail shaft a little.
Beside being able to install larger diameter tires, advantage or dis-advantage of moving front spring eyes rearward? Whats normal or maximum amount allowed? I have read some of 3/4 or one inch. I think it would move rear hangers to a bad angle?

I have been told that on my very stock 69 car. Never considered it as there are "No" mods at all in axle and drive train location. No vibes while driving.
The front yoke of the drive shaft would seem to be to far out as pictured but pure stock! The longer rear balloon tranny seal is not used. What is the real engagement length required? Any one know what that dimension is?

I WOULD MOVE THEM BACK AGAIN IN A HEARTBEAT! IT LOOKS BETTER, WORKS FINE, GIVES MORE ROOM, AND TWELVE POUNDS IS MEANINGLESS!!!BE EVEN BETTER WITH THE WHEELS NOT MOVED BACK !!
