I just got a rearend out of a 60 F100. It measures 60" if I remember right wheel mount to wheel mount.
All 57,58 and 59 passenger cars had the same width axles.Not all wagons had the big bearing ends,mine came out of a 58 wagon,small bearings.I would not put an 8.8 on a scateboard,they are weak,and by the time you fix all their issues you could have a custom 9 inch for your 4.11 pumpkin to fit under your Falcon!!! ROY.
Lincoln Versailles were Falcon (Granada) relatives and had 9-inch rear axles (rear disc brakes too). I suspect it might be easier to find a '57-'59 rear these days, though. -Dave
Here's a picture of the offset yoke and my axles are NOT the same length in the 67 - 77 broncos. Unless the car is super low where the driveshaft is all the way up to the floor I don't think you'll have a problem with the angle of the shaft.
There are 9’’s that will fit your falcon but most of them will be 28 spline. What spline is your 411? If your 31 spline you may as well get any 9’’ housing - narrow it - and have some axles made or stockers re splined. I just got some killer custom axles form Dutchman for my boss’s Dana 60 and was surprised they were only $400 bucks ready to go w bearings. I did the housing myself ….. It was no big deal.
My carrier is 28 spline. I'm not to worried about its weakness, it is a light car and it won't have much traction anyway.
I have a 63 Econlines rear setting on the floor. It is a 9 inch and something tells me it is 61 inches hub to hub
I did a search and found a little info about the Bronco. I have played with the trucks some and only read about the cars. I always though it was going to be one or the other -- equal length axles or centered pinion. Here is what I found though for small bearing Broncos: RH axle is 29-5/8" LH is 27-1/4. That's only 2-3/8" difference (if I did my math right), or some hybrid of the 2 extremes of centered pinion and equal length axles. Based on proportions from Drive Em's info that would have the pinion off center by about 1-3/16" (just like you said in the other post you listed above ) You're right, that may be enough to fit everything where it needs to be.
well I guess I'm not completely brain dead yet. My memory was telling me that the axles were different lengths in the Broncs and by golly it was right. After all this though, the information posted throughout this thread concludes that the axle lengths don't really make a difference.
The early Econolines were little 7.5" rear ends - the weakest Ford made. As for 8.8" not being strong enough. I worked with a guy who ran a 79 Mustang Drag Radial car that ran 9.50's without any issues on the 8.8 with just the usual bolt in stuff Limited Slip, aftermarket axles, good gears.
Yeah, I was really confused by the offset pinion AND the different length axles, but now it makes sense. The main point is that you don't have to worry about the different length axles because most of the cars had different length axles so that they could center the pinion in the tunnel.
