The E-body spring perch centers are 46", there is no housing with 46" centers that is narrower.

Is there a shorter 8 3/4 rear end that will bolts in to an E-Body? Or should i just get the Offset spring mounts and move the perch? Wanting to get a larger tire in the rear. thanks There's no bolt in E body axle swap per say, it depends on where you want your wheel/rim offset/back spacing, if your looking for a more positive or neutral offset on a set of wider rims you could move the perches on the E body axle inboard along with a spring relocation set up... If your looking for more negative wheel offset on wider rims you can use the spring inboard relocation set up that allows you to bolt in the narrower stock 68-70 B body axle You need to determine your rim offset choice first

Gotcha, didn't give that any thought yet, but if i do the B body rear and 1" offset spring kit will i be shooting myself in the foot for harder to get wheels? Is there a shorter 8 3/4 rear end that will bolts in to an E-Body? Or should i just get the Offset spring mounts and move the perch?

I had the perches cut off a B-body rear and new ones welded on at the 46 inch spec. If you are running a factory sway bar that is the way to go. Using offset shackles to move the springs will throw off your end link geometry.
No sway bar or aftermarket sway bar then the shackles are the way to go.
I'd suggest really planning out your wheel tire combo before swapping rears. I think someone makes a tool you can bolt to the axle and adjust to simulate different tire and rim combinations and then rotate it to see if it hits anything. Measure twice, swap parts once... or something like that

I put a b unit into my 70 e. Cut off the perches and placed them where they needed to be. You gain 3/4" per side clearance between the sidewall of the tire and the outer lip on the quarter. Tons of clearance for what I had on the tire/wheel combo of 15x8.5 torq thrusts and 265/50-15 comp t/a's.

I put a rear from 66 b body in our challenger. Bought the offset hangers from doc diff..all bolted right up. Fit a 28x12 m/t tire. On a 15x10 with 5 inch back spacing. No rubbing or cutting anything. Even wheel well molding

For reference, if you install my 1" offset E-body hanger/shackle kit, a '65-'67 B-body rear, drum brakes and 10" wide wheels with 5" of backspacing fit nicely.
A '68-'70 B-body rear, typical disc brakes and 10" wide wheels with 5.5" of backspacing will also fit. What about the previous comment "Using offset shackles to move the springs will throw off your end link geometry."

If I recall hotchkis bars ride under the axle unlike the factory or Firm Feel bars. If you go the offset hanger route substituting a rear sway bar from a B-body to match the width to the new spring location MAY work.

I'm using a 1967 B body rear under a 1971 R/T Challenger with Dr. Diff's offset spring hanger kit. Everything fit perfectly and I'm using 15x10 wheels.
I put the factory sway bar in a big vise and bent each end in slightly, after a few attempts it fit perfectly.

The old Addco rear sway bars are the same for A,B,E bodies they have a more universal attachment. I believe hotchkis offers end links or bracket for Springs that are moved in

Bolting in a a B housing simply eliminates any cutting or welding. that'd be my choice.
