Be sure you buy a quality billet spacer
not a Chinese cast piece.
A hub centric would be best on that big
a spacer. I never go past 1/2 inch myself.
Not trying to talk you out of a sale but
I do not want anyone ever to get hurt
like I did when I hit the Christmas Tree.
I have a couple dozen in back of shop/
By memory = 3 5/16 and 4 7/8 (Might be 4 15/16)
Nothing anywhere close to what you are looking for.
Cragar Super Tricks came 3 1/2 and 4 1/2.
Bob De Vor who ran Centerline would not make custom back
spacings even for the sponsored Racers so I do not think...
I have run a Billet Wheel spacer (NOT Chinese cast junk) with longer
wheel studs and longer lug nuts that go thru the entire wheel and most of
the spacer. This would hedge the problem and I have done that even on my
800 HP+ Scamp (Got to finals in Pinks All Out) which is similar in 1/4s to you...
Well, I never was aware of the 8 1/4 being narrower than the 8 3/4 in A bodys.
I thought that they were both around 56 1/2 drum to drum.
However, I am a strictly a Drag Racer and not a restorer.
Appreciate the information!
How much narrower is it?
The offset shackle kit is an easy deal. Hardest part is
rewelding spring pads which is simple for any welder.
Just do not get housing smoking hot (use wet rags) or it
may warp.
Next option: Calvert Racing makes a narrow one piece spring
that would increase clearance on tires. I used it on my...
I think you will fine with anything up to L60 x 15
as those are a perfect backspacing on my Demons and
Dusters and worked OK on my Swinger 340 which has
a bit small rear 1/4s. If too close buy an offset shackle
kit from Dr. diff to get a bit more space (I think about 3/4
of an inch.

If that is factory 68 superstock Dart those were the original fenderwell
produced on that car. Most of those SS/B cars ran 14 x 32 Slicks as I recall
but some ran a 12.2W x 31.25 if my memory serves. I have owned 3 of them and one was brand new.
I believe someone on this site has mentioned...
I ran 15 x 7 Centerlines with 4 and 7/8 Back spacing on my 64 Dart with a 28 x 9 Radial Slick
I did roll slightly the ft. of bottom of Fender for that tall a tire. I still have the Centerlines = $225.
