What is my best choice for rear axle to replace my Dana60 so I will have 5 lugs on 4 1/2 to match the CV front ifs. Needs to stand up to built 390, with slicks. I saw thread where carcraft 22 had did this but I could not find where spelled out the rearend utilized

 

Welcome to the forums.

My preference is a 9", you can reuse one from a bump(that way it bolts in), then just redrill the axle flanges for 4 1/2" bolt circle(instead of the current 5 1/2"). I think some of the guys are just using a CV 8.8.


My '69 F100 runs a car pattern on the rear for car rims to fit(more choices then truck rims).

 

Thanks for the welcome. Excuse my ignorance I am new to the forum. What do you mean by a Bump

 

67-72 truck is a "bump"(meaning the side of the body has a "bump" in it). The 73-79 were called "dents", due to the valley/dent in the bodyline.

 

Thanks much

 

One other question if I go with a Bump rearend bests ource for disk brake conversion i saw another thread that talked about utilizing a 1997 explorer rearend.

 

I'd just use the 8.8 from the crown vic. Track width would be the same. Or maybe one from an Exploder with Disc brakes.
We have tried to redrill the pickup axles and due to the big hole in them it's real hard to get the new pattern laid out without one stud hole being too close to the big hole.

 

What years did F100's come w/a 9" with 4 1/2" bolt circle wheels?

Some 1980/83 F100's have 5 lug 4 1/2" bolt circle wheels, some have 5 lug 5 1/2" bolt circle wheels.

But, be aware that Crown Vic wheels will not clear the F100's calipers.

8.8" introduced in F100/150's in 1983, but 9's continued to be used thru 1986. If it has an inspection cover, it's an 8.8.

 

Thanks guys,

If you used the cv rear did it bolt up. What did you have to do. ?

Will the 83f150 rear bolt up or are leaf spring perches in difwrent locations?

 

None. But when you work at a machine shop, you redrill them for the car pattern to be able to use a wider variety of wheels. That is what I did to mine 20+ yrs ago.

 

So the stock CV wheels won't fit over the F-100 drum brakes if I redrill the rear axle flanges to utilize 5x4.5 wheels?

Is there any way to make my stock 69 steelies (5x5.5) work on a CV swap?

What's the cheapest and/or easiest solution to get matching wheels on a CV front end swap? I'm trying to stick with a "rat rod" look so stock black wheels w/moonie hub caps & white wall tires is the look I'd like to have but I want a CV front end to get the drop I want.

 

None? Read post 8 again.

 

So I guess I'm looking for an 8.8" from a 1983 F100/150's with an inspection cover, huh? Alrighty then.

 

1983/89 LIGHT Duty F250's also came with the 8.8. The rear brakes are the same as H/D F250's.

 

Number Dummy ,


I believe I have located a 9" rearend out of 83 f150 with 5 on 4 1/2. Have not been able to get to it yet to measure, wondering do you know if the spring perches and the lower shock mounts will match measurements on my 70 f250 so it will bolt in. Without replacing perches or mounts
