Bulletproof Rear-End

A buddy of mine is building a 460 BBF Ford Pinto (500+ Hp) on a budget and need a rearend for it. (there was not one when he got the car) He needs a stout one to handle all that torque. But, since hes on a budget he can't afford to just buy an aftermarket one or have one narrowed and buy new axles. Are there any rearends that are the same (or pretty close) length that can hold up to that 460 BB? He hasn't bought wheels yet so he will be able to offset a slightly wider axle if needed. Any suggestions? Anyone know what width the stock axle is so that I can do some research? Thanks

A 57 to 59 Ford 9 inch is almost a direct bolt in. But, because of their PERFECT width for 32 to 40 Fords, Mustangs and a LOT of other vehicles, they are getting difficult to find I am told.

I, on the other-hand have 5 laid back for spares ( and NO, I do not want to sell one ).

The Lincoln Versaille had a 9" with discs that is close in width, but the Maverick guys have driven those costs up. Start measuring underneath Explorers with the 8.8"

Another thing I learned (from Caroll Shelby himself) is that you can make a small-tube 9" by removing the center section of an 8" and replacing it with a 9" center section. He said that is how he did the first Shelby Mustangs since they had the 8" and there was no 9" at the time that would fit. Some of the Maverick guys do that as well. It just might be a good way to mix and match some junkyard parts and get a 9" that fits

Same here! The next narrowest 9" is the one that was used in the more powerful Mustangs from '67-'70. It's only one inch wider than the '57-'59 unit.

How about a '66-'77 Bronco rear end? By my reseach that it is 3/4" wider than the '57-'59 Ranchero. How wide is the Pinto rear end? This is really what I need to know.

Bulletproof? What's that? Lol. Try a rear out of a Ford Exploder from the 93 up range. Most have 3.73 or 4.10s. I found several with a posi unit and if nothing else you can put a mini spool an open diff. 8.8s are strong enough to handle track duties. I can measure one if you need the dimensions.

The down side of a early Bronco rear end is that the axles are drilled for the Ford truck wheel pattern, not the common Ford car pattern. The pinion is also more offset than a car rear end and MAY make the driveshaft rub the tunnel.

Give me a minute. All I have right now is one with disc brakes. I'll measure that one and get back to you.

Ideally it would ba a Dana 60, but the 9" Ford as some have suggested is a good one to go with.

Hey, sorry for the delay, been under the weather again. My disc brake rear measures exactly 60" from flange to flange. That is the wheel mounting surface. It could be 59.5" if the rotors have moved outward somewhat from the whole rear setting on the rotors. Can't move it now, I feel like a gut with the you-know -what slung out of it.

I found a '71 Maverick 8" on eBay, are the Maverick and the Pinto rear end the same width? The one I found was 57" drum-to-drum. (outside-to-outside I guess is what he means) I'm pretty sure they are I think I've read that somewhere. Just asking to be sure. Anybody know? Thanks
